CS 1.6 Biohazard is a custom build of Counter-Strike 1.6 with a biohazard theme. It keeps the classic gameplay and standard models, and changes the interface to a dark, radiation-hazard style.

Biohazard-themed interface

The menu and in-game windows use dark, moody colors with a radiation-hazard backdrop. The look is the main change here - the gameplay stays the same as standard CS 1.6.

Standard models and server compatibility

The build uses the standard weapon and player models from the Steam version of CS 1.6. Because the models are unchanged, you can join almost any server - public, private or modded - without model conflicts.

  • Server compatibility: standard models work on all CS 1.6 servers.
  • Classic feel: keeps the original look and gameplay.

Server mods to try

CS 1.6 Biohazard works with a wide range of server mods. For a different style, see our CS 1.6 NextGen build. Some popular modes:

  • Zombie Escape: flee from infected players across large maps.
  • Deathmatch: instant respawns for non-stop action.
  • GunGame: switch weapons with each kill.
  • Surf: slide across ramps in a movement challenge.
  • Jailbreak: role-play as prisoners or guards.

Installation

The download is malware-free and installs quickly, so you can get into a match in minutes.
