How zm_303 plays
zm_303 is a Zombie Mod map. Humans buy weapons and weld or block chokepoints to hold off the horde; zombies use speed and knockback-resistant health to break the line. Survive to the end of the round as a human, or infect everyone as a zombie. On Combat Skirmish it runs directly in your browser through WebAssembly — click Play and you are dropped straight onto a live public server, no Steam account or download required.
