After 15 years, Zombie Panic! returns with a stunning Source 2 remake showcased in a new Steam trailer. The asymmetric zombie shooter blends Left 4 Dead chaos with Counter-Strike tactics, letting players fight as humans or spread infection as zombies. Valve-powered visuals elevate the classic formula, promising crossplay across PC and consoles in 2026.
Classic Formula, Source 2 Power
Originally a 2007 Garry’s Mod mode, Zombie Panic! exploded as a standalone Source hit. Humans barricade objectives while zombies claw through defenses in tense matches. The remake keeps core classes – Light/Medium/Heavy survivors versus fast Runners, tanky Shamblers, and explosive Boomers – but amps visuals and netcode.
New maps remix fan favorites like Kerkyra Island and Biotec HQ with destructible environments. Zombies smash barricades smarter; survivors wield upgraded arsenals from pipe bombs to flamethrowers. Infection meter builds tension – get bit too long, turn against your team.
Human vs Zombie Class Breakdown
| Side | Class | Role |
|---|---|---|
| Human | Light | Fast scout, pistols, quick heals |
| Human | Medium | Balanced rifleman, grenades |
| Human | Heavy | Tank with minigun, slow movement |
| Zombie | Runner | Speed demon, leaping attacks |
| Zombie | Shambler | Slow horde builder, claw spam |
| Zombie | Boomer | Explosive vomit, summon adds |
Objective modes like Swarm (zombies vs AI waves) and Elimination (team deathmatch) ensure variety. Trailer teases ranked ladders and custom servers.
From Mod to Multiplatform Glory
Fan devs at No More Room in Hell fame rebuilt Zombie Panic! from scratch in Source 2. Free-to-play model hooks old fans while Steam Workshop revives custom maps. Crossplay unites PC, PS5, Xbox Series X|S, and Switch 2 lobbies.

Trailer music pulses with industrial dread, matching frantic gunfights and zombie rushes perfectly.
Why Zombie Panic Endures
In a battle royale sea, Zombie Panic! thrives on pure asymmetry. Humans coordinate barricades and flanks; zombies swarm with primal fury. No battle passes dilute the chaos – just friends versus undead hordes. Source 2 promises 120fps stability even in 32-player matches.
Community servers host 24/7 classics like Infection mode, where one zombie sparks apocalypse. Ranked play separates casuals from survivors.
