A LOVE LETTER TO EARLY SPLINTER CELL GAMES

You just entered the warehouse through the vent shaft as you hear voices from outside. They know you’re here. Someone must have tipped them off.

You continue to stay in the shadows. You shoot out lights, flip off circuit breakers and lockpick doors. You are a silent assassin.

You distract the guards by throwing bottles or imitating their wives voices. One by one you pick their lights out.



Fuck. You’ve been compromised. You shoot out the next door lock and go in guns-blazing. In an adrenaline filled shootout you eliminate your target and barely manage to escape. Well done!



Enter the world of Intravenous as Steve Robbins - a man set out for revenge after losing his brother to low-life junkies. Delve deep into the criminal world under the guise of darkness or go armed to the teeth, guns-blazing, and padded with armor.

• Old-school stealth. Your visibility depends on how well-lit the environment is, and every step you take makes noise.
  
• Teeth-grinding action. Fun stealth gameplay does not exclude fun gunplay. Intravenous is meticulously designed to offer stealth for those looking for it, as well as no-brakes gunplay to those itching for a gunfight.
  
• Reactive AI. Your enemies will do more than just rush straight at you. If they've found a dead body they will alert their friends in hopes of finding you. If they hear you sneaking about, they will investigate. If they see you, they will open fire. If they're unarmed, they will try to find their friends and warn them of you.
  
• Capable enemies. Enemies take cover during gunfights, use flashlights in darkness, and radio in suspicious activity. Any misstep you make will result in your opponents responding appropriately.
  
• Lots of weapons. Multiple weapons, each with their unique handling. Each works best in a specific situation. You're sure to find your personal favorite here.
  
• Choose your loadout. Pick a rifle, a pistol, and a bulletproof vest to be ready for combat, or just a pistol and naught else, to be quick, agile, and silent- ready for improvisation.
  
• Adapt to your surroundings. Shoot lights out, crawl through vent shafts, flip circuit breakers off, throw bottles to distract your foes, lockpick doors to find alternative ways in - or simply shoot the door lock out, and go in guns-blazing.
  
• A gritty story. Steve Robbins lost the single most important person in his life - his brother. With aid from a mysterious person claiming to have suffered a similar fate, he decides it's time to take matters into his own hands after the police turns up empty-handed. Nothing is as clear cut as it seems to be.
  
• Uncapped frames per second. 60hz display? Yep. 144hz? No problem. Enjoy the swift action or edge-of-the-seat stealth on your preferred monitor refresh rate.
  

Update 1.4.0.4 (30/01/2023)

• fixed fake shadows ceasing to render when following a certain order of actions
• fixed vent entry visuals being glitched due to an oversight related to the updated fake shadows rendering system

---

---

Update 1.4.0.2 (20/01/2023)

• fixed incorrect body scan range for enemy AI (they saw half the distance that they should have)
• fixed grenades causing a crash when following a very specific order of actions

---

Update 1.4.0.1 (05/01/2023)

• fixed Saiga-12K having the AK-103's minimum damage value, which meant that once the projectiles went past their effective range, the damage would increase instead of decrease
• fixed some of the assets being mis-named as uppercase in the objects texture atlas, resulting in them being replaced with a "missing texture" sprite

---

Update 1.4.0

Additions

• new gadget - Medkit:
• it can heal a total of 40 health points
• does not contribute to bandage use limit
• new gadget - PKC-EMP:
  • disrupts eletrical devices in a radius around the player
  • recharges quickly only when moving
• new graphical setting - High-contrast rendering:
  • enabling this will switch to a different light-blending algorithm, one that will make details pop more
  • it should have no performance difference compared to when disabled

Visual improvements

• added visual recoil from firing weapons
• added blast effects for grenades and when using the HSR-EMP
• improved night-vision goggles effect
• improved fake shadows to be able to cast shadows on top of each other, while using fewer CPU and GPU resources
• shader and lighting system optimizations; in GPU-bottlenecked scenarios testing showed an average improvement of 23%, owing largely to the lighting system optimizations, with the lowest and highest improvements ranging from 14% to 38.8% better performance - the boost in performance you'll see will largely depend on your graphics card!
• improved menu blur - looks better and uses fewer GPU resources
• added a background panel to the loadout menu, so that it doesn't look like it's "floating"

Gameplay tweaks

• improved light level calculation by evaluating the grayscale value of the light, rather than the sum average - dark areas are now darker, while bright areas remain just as bright, if not brighter
• increased armor protection in the event of the projectile failing to penetrate the armor vest - the further the bullet is from penetrating the vest, the greater the damage dampening

Fixes

• fixed incorrect shot spread increase calculation
• fixed being able to go prone while cooking or throwing grenades
• fixed a crash that occured during cutscenes with the "Exploding Enemies" mutator enabled

Update 1.3 (20/12/2021)

New gameplay mutators

Remember that sole "Auto-grab ammo" checkbox? That's what I call a "gameplay mutator". Despite having a system for them in place, I didn't have the time nor the ideas for more of these - polishing and preparing for release took priority. Now that the game's out, this means I could finally go back to these and add more of them. You'll find the update brings 14 new gameplay mutators.

Among these is a magazine system for all you realism lovers; a currency system for the loadouts intended to make the start of the game harder, since you have access to far less gear with it enabled, and some silly inclusions like exploding enemies, sawn-off shotguns for everyone, and more.

Don't worry, as these mutators are optional, your existing playthrough savefiles will remain as they were.

Rain

One feature I wanted to have on release, but once again didn't have the time for, is rain... update 1.3 takes care of that! It is enabled on five levels in the base game campaign. If you wish to find out which those are - check the changelog available further down in this announcement.

Rain in Intravenous isn't just a visual thing - it increases the ambient noise level when present, allowing you to get away with more noise when moving around, or taking enemies out. Rain not only changes the way the levels are played, but also changes the feel of the levels themselves. Don't want/like rain? Have no fear - you can turn it off using one of the newly-added gameplay mutators. :) Want rain on every level? No problem, there is a newly-added gameplay mutator for that, too!

New tonemap option

You'd be surprised at how much of a difference something as simple as a tonemapper can make for a game's visuals. Update 1.3 brings a new 'filmic' tonemapper - it amps up the contrast on the image, making bright areas pop, while the darker areas remain close to how they were before. If you've played Intravenous before, then when you first launch version 1.3, it will use the new tonemapper. As with a lot of things in Intravenous - this is an optional setting, so if you find that you prefer the old one, simply switch to it in the options menu!

The full changelog

• added rain:
  • it increases the ambient noise level, both inside and outside of buildings (more outside than inside), allowing the player to sneak around with less effort
  • it is present on the following levels in the base campaign: , , , , and
  • can select whether falling rain droplets should be affected by lighting in the options menu - no impact on performance, this is purely a preferential choice
• added new gameplay mutators:
  • Magazine system - when enabled, players will need to manually load magazines with ammo. Reloads will no longer replenish ammo instantaneously.
  • Bankrupt Accomplice - when enabled, the equipment present in the loadout menu will be very limited. You'll need to find and exfiltrate with weapons in your possession if you wish to use them for the next missions. This setting completely ignores the weapons you've unlocked on your previous playthroughs.
  • Currency system - requires Bankrupt Accomplice to be enabled; when enabled - even more weapons become unavailable. In addition to exfiltrating with weapons in your possession, you will be able to spend money, which you earn by completing the campaign missions, to unlock weapons. Those looking for more "graded" progression equipment-wise should like this one.
  • Sawn-off shotguns for everyone - what it says on the tin. Are you a bad enough dude to go against an army of sawn-off shotgun wielding goons?
  • Desert Eagles for everyone - same as the sawn-off mutator. Combines well with the "Very Unfair" weapon randomization difficulty option.
  • Ricochet party - bullets always ricochet off surfaces. try not to kill yourself with your own bullets, eh?
  • Exploding enemies - when enemies die, they explode. Doesn't apply to non-lethal neutralizations. A practical way of enforcing a non-lethal playthrough... I think.
  • Blinding enemies - same as exploding enemies, except they blind everyone around them.
  • Always rainy - rain is present on all levels where it is possible for it to be present. Makes stealth easier, as the sound of rain masks the player's noise.
  • Never rainy - does the opposite of "always rainy". This one seemed necessary, since there is rain in the base game campaign now :)
  • Coin-flip rain - 50/50 chance on whether rain will be present.
  • Dynamic rain - rain might start as you're playing through a level... or it might not
  • Enemies always alert - enemies start out in their alert state.
  • Waking enemies - unconscious enemies will not remain knocked out forever.
• added a new tonemap option to the options menu - players can switch between the default and the new, filmic, tonemap
• added a gunfire noise slider to custom difficulties
• russian localization tweaks
• german localization improvements
• savefile previews now list mutators used on the savefile (requires you to save at least once on old savefiles for them to show!)
• minor CPU optimizations
• fixed the player character swearing on the last level when dead
• fixed one of the broken windows in 'Druggie Ghetto' being unclimbable
• fixed the aim line disappearing when there is an object the player can interact with
• fixed aim object outline disappearing at times
• fixed environment sounds that fade in/out always starting out with volume at 100%, resulting in an audible "on" sound for a single frame when it starts playing
• fixed player-unbound actions being reset back to their default keys when starting the game
• fixed actors going to the "aim" animation instead of "idle breathe" animation after finishing a reload with a variable-reload weapon (ie. VP9, Remington 870)
• fixed being able to interact with doors/objects while climbing over things
• fixed the ambient sound volume slider not functioning properly (not affecting the actual sound levels)
• shell casings should no longer remain active forever (emitting a lot of sounds while they're at it) in some certain cases

Controller support

You've asked for it and I've added it! While Intravenous was made with keyboard & mouse controls in mind, you can now play it with a controller. Whether you can be as proficient with a controller as you can be with a keyboard & mouse - that is the question! But don't take my word for it - I barely play games with a controller, so I wouldn't know how easy or difficult it is to play Intravenous with one. However, keyboard and mouse is still the optimal way to play Intravenous.

Tactical reloads

These allow you to reload your weapon faster, by dropping the current magazine to the ground, instead of sticking it back into a mag pouch. The downside? You lose the ammo present in the magazine, and have to pick it back up in order to get the ammo that's in the magazine.

Custom difficulties

Allowing you to customize the difficulty you play on, as well enable or disable randomization of certain factors - now you can set one up that you have the most fun playing with. While the 'True' difficulty will always remain the intended difficulty, it's up to you to decide what your perfect difficulty is with custom difficulties. You can adjust almost any aspect of the game: damage received, noise made, enemy vision range, along with randomization of things like the weapons that enemies have, and their experience levels!

Improved shadow filtering

I love optimizing my code, and always try to give players the best possible performance without sacrificing on quality. Better visuals AND better performance is a deal I could not pass up. Not only do shadows look better now on settings above 'Rough', but they also use less of your GPU and CPU! The 'Normal' setting now uses up to 20% less graphics power when compared to the old 'Normal' setting, and puts out an image comparable, or better than, the old 'Soft' setting! Meanwhile the new 'Soft' setting uses up to 10% less graphics power compared to the old 'Soft' setting, and puts out a far better-looking image than the old 'Soft' setting! In addition, I've added another setting - 'Ultra'. This one's for smooth shadow lovers and cranks up filtering even higher, to make shadows look even softer. In practice it performs about on par with the old 'Soft', but looks way, way better than any setting that was there before.

That about wraps it up for the big new things that this update brings! The rest of the changes are, as usual, various tweaks, minor improvements - the type of stuff you usually see in the small patches that I release. :)

As is the case with any large update I release - I am always listening to the community, and if someone has a suggestion on how to make certain things more comfortable - I always take such suggestions into consideration. The same principle will also apply to controller support suggestions, as I never play with a controller.

Full changelog

• added controller support

• added tactical reloads:

• a faster type of reload which results in the non-empty magazine being dropped to the ground

• enabled by activating one of the control schemes in the "Allow tactical reloads?" dropdown box in the options menu

• three types of tactical reload control schemes: regular (press to tac-reload), inverse (hold to tac-reload), double-tap

• player weapon handling balancing:

• AK-103, AK-107, Saiga-12K non-empty reload time increased to 1.9 seconds (was 1.7 seconds)

• MP5 empty mag, chamber ready reload time decreased to 1.3 seconds (was 1.6 seconds)

• Mini-uzi non-empty reload time increased to 1.9 seconds (was 1.6 seconds)

• weapon spread increase from firing decreased by 20% for the player

• improved and optimized shadow filtering:

• settings above "Rough" now produce a much better result, including penumbra simulation, for very smooth shadow fall-off near the edges of a light caster

• "Normal" quality now produces a visual result on par with, or better than, the previous "Soft" setting while using up to 20% less GPU power than the previous "Normal" setting

• "Soft" quality now produces a visual result far better than previously, while using up to 10% less GPU power

• a new shadow filtering quality setting - "Ultra" - has been added, it increases the penumbra quality, at the expense of increased GPU usage

• added custom, adjustable difficulties:

• players can adjust damage rates, armor degrade speed, savefile counts, and many other things

• it also adds the ability to randomize the weapons and experience levels of enemies on the levels, allowing for gunfights that play out completely differently on any given level!

• retroactive change of difficulty on in-progress playthroughs is not possible, you'll need to start a new playthrough with a custom difficulty if you wish to play through the game with your personal difficulty mode

• added a UI element hint when choking an enemy, to keep holding down the choke key to grab the body upon finishing the choke

• unconscious/dead bodies are now a little bit darker, so that they blend in more with the background, to make it easier for the player to see whether there is someone still alive in a place with a lot of dead bodies

• 'Easy' and 'Normal' difficulties now increase the protection provided by armor by 40% and 20%, respectively

• when picking up ammo, the ammo pick up element will now fill up to display how close you are to carrying the maximum amount of ammo for that ammo type

• when taking damage in 'Masochist' difficulty, and in any custom difficulty that has insta-death enabled, the 'hurt' effect will now show even if the player survived the attack due to body armor

• when armor vests break, a distinct sound will now be played to communicate to the player that something has just happened

• using a bandage now plays a sound effect

• the "unload nearby weapons" action will now ignore objects the ammo of which the player is full of, preventing a bug which caused the player to not unload nearby weapons of a different caliber, if the system decided to pick a weapon loaded with a caliber that the player has maxed out ammo in their inventory

• in the New Game+ menu the unlocked weapon list is now sorted by alphabet, in order to be easier to read and spot differences

• clicking any button but the "skip cutscene button" will now show the "hold [key] to skip cutscene" UI prompt during a cutscene

• limiting the amount of times a "hit" sound can be played on the player to 3 sounds max., to prevent them from overpowering the newly-added "armor break" sound

• russian and turkish localization tweaks

• various minor UI tweaks

• fixed some events causing the player to update their movement speed while moving, resulting in cases where the player would suddenly stop firing while running at top speed

• fixed the custom level campaign unlocking the 'Gun Nut' achievement (should be reserved only for the main campaign)

• fixed opening the campaign level list deselecting the campaign
