Bosses & Enemies

Boss roster and badges

Each main boss has an official Roblox badge for beating it. Several of those badges also raise your rank, which is why most players end up fighting all of them. D-Zero is the exception: there is no badge for him, and in most places you can’t kill him at all.

Rare enemies with badges

• WOLF_IN_SHEEPSHEAD: kill a Deceiver. Fandom says Deceivers show as green dots on your radar.
• UNRECOGNIZABLE: neutralize an enemy the official text blanks out. Miraheze names it the Leaper, which waits behind a flesh cage in Reactor 4 until the cage is burnt. Fandom describes a rare, fully mutated enemy there without naming it.
• WAR-CRIMINAL: shoot a Rasonian combat medic while it is healing a soldier.

Gilbert

Gilbert is the first boss most squads meet: an infected MGF Pointman with an R8 shotgun, waiting in the Generator 2 room in Sector 1. Fandom says he has to die before that generator, the one that opens the way to Sector 2, can be switched on, and that he respawns 15 minutes after each kill. His health scales with the number of players in the server. Fandom’s own pages give different totals, so we don’t quote one.

• Stay at range. The shotgun can kill you outright up close, and when you get near he rushes in with his knife.
• Make him miss. He leads his shots, so changing direction mid-strafe throws off his aim. Lean around cover with Q and E.
• Shoot, don’t bash. Gunfire staggers him briefly and he can’t fire while staggered or reloading. A bash doesn’t stun him.
• Watch for phase 2. Fandom says that below half health he gets faster and fires faster. Miraheze puts the switch at 250 HP: his helmet breaks, he heals back to 750 and is invincible for about three seconds, then rushes you more often, though more slowly. In this phase he is outlined through walls, so you can find him again.

He also shoots other infected, though he goes for players first, and he never attacks Chimera. Miraheze adds that he drops his R8 when he dies, and only a Breacher or Pointman can pick it up. The Underequipped route covers luring him away from Generator 2 on a solo run.

Chimera

Chimera is Kayden Troy, Gilbert’s old squad leader, fused into a modified exoskeleton. He is the boss that hunts you across the facility. Opening the Basement valve in Reactor 4 starts a timer; when it runs out, a site-wide alarm and a long screech announce him; Miraheze says he drops from a hole in the ceiling of a corridor near Generator 2. The wikis report different timings, so treat the valve as the trigger rather than planning around a number. Near him your screen darkens, static and flashes of light build up, and his theme starts.

Slash

Fast claw strikes at close range. Keep moving and don’t trade hits.

Dropkick

A short wind-up with a burst of static, then a lunge that knocks you down. Break line of sight during the wind-up.

Surge

When about three players crowd him, he punches the floor and sends out two shock waves. Back away as he winds up.

Execution warp

A longer charging sound, then he teleports to a player he can see and kills them outright. Get behind cover as soon as you hear it.

• No bash stuns. Bashing him makes him clash back, reflecting a little damage onto you.
• Fire in bursts. Bullets can put him in a dodge state that cancels their damage, and he is immune while taunting. The community Trello says headshots from the R-12 and AEN-50 do nothing to him; see the weapon crates guide. Miraheze adds that he ignores any single hit above 300 damage.
• Back off at half health. He drops to his knees, then gets up enraged: faster and hitting harder.
• Carry an axe. If he tries to execute you while you hold one, you fight him off once, but the axe is used up. Miraheze says the Pointman’s Halligan bar, which otherwise works like an axe, doesn’t trigger this.
• Stay clear at the end. His exoskeleton explodes. Fandom puts the blast a few seconds after the death animation; Miraheze says he kneels at 500 HP and sets it off himself, hitting everything within about 30 studs.

SIN (Sinitzyn Komarek)

SIN commands the Rasonian Infantry Forces garrison in Sector 3 and arrived with the Sector 3 update in late November 2025. While you work through the sector he jams your radio link to TOC Bill and taunts you, then waits with his soldiers in the large rooms past the keycard door. Fandom and Miraheze both give him 4,000 HP over two phases.

Phase 1: armored machine gunner

He moves slowly and fires an RPD machine gun whose hits can knock you down, and he kicks anyone who gets close. The helmet makes his head bulletproof from the front and his chest is armored, so aim for arms and legs, and don’t stay in his line of fire: several hits in quick succession stagger you.

Phase 2: sledgehammer

At half health the helmet and the RPD come off. He draws a sledgehammer and runs at you slightly faster than you can sprint, but headshots now land. Each swing slows him for a moment; use it to back off and reload. He also heals every time he executes a player.

Miraheze adds that bashes, tasers and axes do nothing to him, and that when he tries to execute a Leader, a quick-time event starts instead: hit every key shown and the Leader survives.

The Cerberus and the Vorax

The Cerberus is a Rasonian BTR-82A armored vehicle in the Sector 3 Vehicle Depot. Reaching it earns ROLLING_STEEL and taking part in destroying it earns BRAZEN_BULL. Only AT-7 rockets and C4 can damage it, and its health scales with the server. The full breakdown, with HP by player count and both phases, is in the Cerberus boss guide.

A Vorax spits blood that damages you quickly over time, and Miraheze says it explodes a couple of seconds after it dies, so step back. Neutralizing one earns UPCHUCK. Fandom’s October 15 Achievements edit and Miraheze’s Vorax page place it in Sectors 1 and 3; Miraheze’s badge list still says Sector 2. These are community locations, not an independently checked spawn map.

D-Zero

D-Zero isn’t fought like the others. In the Tunnels he stalks you: sometimes he only appears and retreats, sometimes he starts a chase. If he catches you, you must clear a quick-time struggle without a single mistake or the run ends. At the end of Yuri’s simulation he is the final obstacle, immune to everything except backstabs. Tactics for each are in the Tunnels guide and the Night Stalker guide.

Mikhail, Dave and Vladimir

MIKHAIL WILLIAM · SECTOR 2 LOGISTICS · 1,750–1,800 HP

An infected firefighter with a circular saw, found mourning another firefighter. He stays passive if you crouch past; the Underequipped route uses this. Shoot him a few times and he screeches and charges. Bashes don’t work on him. Keep looping away, reload while he walks, and aim for the head. He is a target in Tachyon’s second batch.

DAVE · SECTOR 3 · 1,200 HP

A black RSU hazmat suit and a chainsaw, in the hallways where you destroy ammo caches. He parries your shots about five times, then charges. Shoot him while he charges, when he can’t parry, and again when he stops to restart the saw. Fandom says hits stagger him during the charge; Miraheze says gunfire never staggers him.

VLADIMIR BZOCHVENYICH · RIF COMBAT ENGINEER

An armored infected that lays landmines as he walks. Touching one kills you instantly. Walk around them or shoot them from a distance; his armor resists bullets.

Fandom gives Mikhail 1,750 HP and Miraheze 1,800. Mikhail and Dave also appear in Yuri’s simulation at kill milestones, with different health there.

Common infected

These make up most of every run. Health values are from Fandom’s Hostiles page. Its damage figures don’t match Fandom’s Enemies page, so we leave damage out.

Community figures from September 26, 2026. Balance patches change them.

When a player turns

A player who is infected and succumbs comes back as a hostile infected, dangerous to their own squad. Which form depends on what they carried and which class they played:

• MGF Viral. Dodges like a Riser, explodes for 50 damage when it dies, and dies on its own after two and a half minutes.
• Viral Executioner. What a player carrying an axe becomes: 1,500 HP, a one-hit kill, and gunfire doesn’t stagger it. Keep your distance and empty magazines into it.
• Viral Leader. An infected Leader or Commander. It fights with a knife and enrages nearby infected, which gain Viral traits.

A player with a class equipped has a small chance (Fandom says 10%) to become a controllable infected instead, still under their own control. Tachyon’s quest reward makes that outcome guaranteed.
