Worth buying? What 300 Steam reviews say.

US Steam price, checked 1 h ago

The verdict

A free, classic Source-mod zombie PvP game with tense human-vs-zombie teamwork and barricades. Skip it if you need a populated server or solo play: the playerbase is tiny and there are no working bots.

Great for

Nostalgic players and friend groups who want free, team-based human vs zombie multiplayer on Source

Main risk

Few or no players online, no working bots, so you may not find a real match

What players love

New dev team's updates ruined the game

Mentioned in ~1 in 4 negative reviews

“This game was ruined after the unneccesary update 3.0. Melee weapons have become clunky and slow and have horrible hit register now.”
