While the legendary Splinter Cell series is gathering dust in oblivion, and Sam Fisher can only be found in the form of collaborations and skins in other projects, the genre of classic stealth is going through hard times. Hideo Kojima is experimenting with courier simulators, and Commandos is getting a remaster with stripped-down symbols and a postponement of the release date for the new part of Commandos Origin, where even the demo shows excessive linearity of levels. Against this background, the Intravenous project became an unexpected discovery — a real greeting from the golden era of stealth action games.

Intravenous (translated as “intravenous”) is a 2021 top-down stealth action game created with love for the old-school genre. The main character is a young man named Steve Robbins, who finds himself embroiled in a dangerous war with the criminal underworld. He has to deal with gangs, mercenaries, drug dealers and other dark representatives of the streets. Each enemy has their own habits and weaknesses, but Steve is adept at using stealth to trick, neutralize, or circumvent them.

The game combines a tense atmosphere with a tactical approach: you need to be careful, plan your steps and be able to disappear into the shadows. That’s why Intravenous is called a real gem of classic stealth — a rare example of how you can bring back the spirit of the genre without slipping into arcade or excessive linearity.

At first glance, the story in Intravenous seems classic and unremarkable: a tale of revenge. The protagonist, Steve Robbinson, tries to numb the pain of loss in the most radical way possible—by shedding the blood of those who could in some way be connected to his tragedy.

The writers try to surprise the player—the story has several unexpected twists, though experienced viewers will anticipate them long before the ending. Near the end, the plot branches slightly, but all paths still lead to the same outcome. And this makes practical sense: this structure is ideal for sequels, and it’s no surprise that Intravenous 2 was released three years later, in the summer of 2024.

The dialogue is deliberately crude: abundant slang and expletives. Given the grim setting, this feels natural and could have contributed greatly to the atmosphere if the game had full voice acting. But it doesn’t. As a result, we read dry text on the screen—and instead of immersion, we often feel slightly tired.

The lack of voices is especially noticeable during cutscenes: characters appear as small portraits, and their lines are displayed over the game level in a top-down perspective. But this isn’t limited to story-driven dialogue. Even random NPC conversations during missions are conveyed through text.

You can “overhear” the chatter of two bandits cursing at the boss, each other, or the protagonist. Sometimes it’s amusing, but the effect isn’t what you’re expecting. When ominous music plays and the screen is blank, the player is left wondering whether the enemies noticed something suspicious, or whether the camera detected movement and a guard went to check the corridors.

To their credit, the enemies in Intravenous constantly communicate with each other. They call for backup, discuss what’s happening, shout threats at the hero, panic when they sense they might be the next victim, and take defensive positions. All of this can only be read from within the camera’s field of view. And yet, voiceovers here could have been a real breath of fresh air, heightening the tension and making the atmosphere much more lively.

Intravenous Game Mechanics Overview

Intravenous is the case when you realize from the very first minutes that there will be no easy walk. The game looks down at you, as if it’s saying, “Are you ready?” Everything seems to be clear and visible, but it immediately turns out that there are a minimum of hints. There is no map, no convenient enemy diagrams, and the interface is deliberately empty. Do you want to survive? You really have to walk through dark corridors, listen, memorize the route and be a scout for yourself.

Light and shadow are your best friends (and worst enemies)

All stealth is based on playing with light. And here Intravenous resembles the old school, the one where every lamp decides your fate. All missions take place at night, and you learn to enjoy every light bulb turned off, every shadowy corner. Somewhere you can flip a switch, somewhere you can crack a flap, and sometimes you have to go to extreme measures – shoot at a lamp or even bang it with a grenade. The lamp will explode, the room will plunge into darkness … and then the heart stops, because the light can return flickering, treacherous, betraying your silhouette.

This game literally makes you feel like a baby rat, sneaking through someone else’s basements.

Body containers and a sense of the absurd

To be fair, Intravenous doesn’t always play fair. They teach you in training that corpses should be hidden in containers. Everything is logical… until you find out that there are only three containers on the level with fifty bandits. And each one accommodates only one. At such moments, you want to grab your head: “Seriously?”. As a result, you stop even paying attention to these boxes — they are of zero use. And then the old Commandos come back to mind, where you could push the enemy under the bed or throw him out the window.

This is sorely lacking here.

Lying in the shade doesn’t mean you’re safe.

At the very beginning, they teach you: if you want to survive, lie down in the shade. Sounds cool, right? But here’s the problem: lying down, your hero is as helpless as a newborn. Neither shoot, nor throw a knife, nor strike back. And if the enemy suspects something is wrong and lights up with a flashlight, that’s it, you’ve played. They’ll just shoot you, and you won’t even be able to make a sound.

At such moments, you catch yourself thinking: the game breaks its own rules. And it gets frustrating, because the mechanics seem interesting, but it’s scary to use it.

Details that catch on

But it’s worth admitting: the little things work great here. Traces of blood, for example. If an enemy is killed and then the body is dragged, a path remains, and others may notice it. And if you just knock them out and take them away without blood, the chance of being discovered decreases. It would seem like a small thing, but it’s these details that create a real stealth atmosphere.

However, closer to the end, the developers are breaking everything they built again. The hero starts automatically finishing off all stunned enemies, and you are no longer in control of the situation. Instead of a neat operation, it turns out to be a bloodbath — and all your caution turns out to be in vain.

Noise, guns, and “deaf” pistols

The silenced pistol in Intravenous is a separate song. You think, “Oh, finally a weapon for quiet operations.” But in fact, half of the level hears the shot. You shoot in the street, and the enemy gets up through two corridors and two doors and goes to check the noise. And not alone, but with a friend.

As a result, you realize that real stealth is a knife, a taser, strangulation or hand—to-hand combat. Even a falling body can attract attention if the difficulty level is high. That is, every step, every choice is a risk. And then there’s that feeling of tension that we love the genre for.

Doors and lock picks are a lost opportunity

The door system in the game is controversial. In the first mission, you’re looking for keys, and it’s cool: you walk around, rummage through the rooms, find a bunch, and open the door with relief. But then they give you lockpicks, and almost everything boils down to hacking or banal knocking out. The keys lose their value, and exploring locations becomes a little less interesting. It’s a pity, because there was a lot of potential in this mechanic.

Level Balance in Intravenous

Different difficulty levels transform each playthrough into a completely different experience. On high settings, the game offers almost no respite: there are fewer saves per mission (and the missions, remember, are enormous), and enemies react more acutely to the slightest noise and any suspicious action. On easy mode, however, everything feels much calmer—the “infinite number of saves remaining” message relieves the tension and allows you to relax.

It’s also important to remember the realism: here, a single miss can decide everything. Both the enemy and the protagonist can die from a couple of bullets. Even a one-on-one encounter can end with the death of Steve, the hero who is tasked with the role of “cleaner.”

The game mechanics do not forgive recklessness. You can try to distract the bandit by throwing an object to lure him into a trap. But there are no guarantees: the enemy might not take the bait, but instead become wary, call for backup, and raise the alarm. And the most disturbing thing is that the anxiety doesn’t subside over time. Enemies stop idly sitting in front of the TV or staring out the windows, start patrolling in pairs, setting ambushes. One wrong move, and your stealth is ruined.

Enemies monitor literally everything. Turned off the lights in a room? If a passing gangster saw the lights there before, he’ll definitely check what happened. Sometimes, they’ll even go to the fuse box if the switch isn’t working. They also notice open doors that weren’t there before, react to the sound of footsteps, gunshots, the sound of broken glass, or fresh blood stains. And if two guards are standing next to each other and suddenly one disappears, the other panics and rushes to look for him.

There are, of course, strange exceptions. For example, a weapon left on the floor after the death of a comrade goes unnoticed. But glass is a different story. If the enemy didn’t see it break, the mere fact of the window breaking won’t faze them. But it’s precisely through a broken window that sounds travel further, and any suspicious movement becomes more noticeable.

So a small detail you overlooked can easily turn into a problem, capable of ruining an entire, perfectly planned mission.

Why Intravenous is the best choice for stealth action fans

The game doesn’t punish you for flagrantly breaking stealth—sometimes it’s even fun. For example, you can cut off the power to a building, and then, while people are scurrying through the dark corridors with flashlights trying to turn on the lights, calmly enter and wreak havoc: machine gun fire, flashbangs, and grenades accompanied by driving music—the scene is cinematic and incredibly adrenaline-pumping.

The control settings add a touch of hardcore. In the menu, you can choose “tank” controls or a more convenient option. Enable tactical reloading—it speeds up magazine changes, but the character drops the partially filled clip on the floor. After the battle, you can pick it up and restore your ammo. There’s also an option for automatic ammo pickup, or a manual mode where you press a separate button to pick up ammo. These little touches make the gameplay more thoughtful and force you to think not only about firefights but also about equipment management.

Sometimes the game throws up inconveniences that feel like part of the hardcore gameplay: maps with unclear navigation—there may be no objective markers, forcing you to wander until you find the right building or room. Another controversial aspect is the mouse wheel, which both regulates movement speed and switches environmental interactions. This leads to absurd moments: you want to break into a run, but there’s a corpse or item lying nearby—you turn the wheel up, and instead of speeding up, you scroll through the interaction menu and keep crawling. These little details are annoying, but they also add to the feeling of a living world.

Intravenous is capable of setting the player up for tactical traps you won’t find in typical stealth games: when alerted, enemies from across the level converge on the source of the noise, attempting to overwhelm you with sheer numbers. However, these waves aren’t always lethal—if you’ve dealt with a crowd in front of witnesses, the remaining fighters will more often try to flank, hide, or wait for an opportune moment rather than launch a frontal assault. And if the enemies are grouped together, you can exploit this: pelt them with grenades (live or flashbang), blind them, and they’ll start shooting at their own.

The enemy AI also has limitations: enemies don’t climb through vents, fences, or windows—their path is simple and predictable: door, flank, door again, or look out the window. This gives you room to plan: knowing their movements, you can set an ambush or open fire at an opportune moment.

The game features two opposing achievement types: “kill everyone” and “kill no one.” This means you don’t have to completely clear a level—you can flank everyone and complete the objective bloodlessly. But keep in mind that keeping the “homeless and drug addicts” alive is significantly more difficult. Non-lethal weapons are extremely scarce: a three-dart tranquilizer and a multi-charge taser are rare. The challenge lies not only in not killing enemies, but also in keeping innocents alive when it seems there’s no motivation to do so.

The main options for completing missions are:

• Clear all enemies and turn the level into an arena of chaos;
• Complete the stealth mission without touching a single enemy;
• Use a combination approach, neutralizing some enemies while outflanking the rest.

In reality, this means that many missions require flanking, stunning, and melee neutralization—and with limited ammo and scarce ammunition for non-lethal weapons, this becomes a skill in itself. The higher the difficulty, the fewer available saves per mission; on lower difficulties, saving is easier, but the enemies are more resilient. Therefore, the optimal tactic is to remain low-key and carefully plan every step: map out your route, ensure you have ammo, and have an escape plan. Otherwise, take the risk and you’ll quickly descend into full-blown, bloody action with a beat-’em-up beat.

Ultimately, Intravenous offers a hybrid: the freedom to unleash carnage and the deep tactical gameplay of a stealth variant. You’re given tools—from grenades and tranquilizers to clever control settings—and decide who you want to be: a quiet cover artist or a gunfight rock star.
