TOXICANT - Coming Soon: Rampage! Playtest - Steam News
Greetings! You may have noticed the playtest button that quietly appeared on the store page and be wondering what that’s for. In this update I will tell you all about it, but first, a bit of history: With TOXICANT I set out to make game that wasn’t just another zombie shooter. Instead, I wanted to focus on more on evasion, and much of the design is based around this (tunnels, stealth buffs/debuffs, stamina, etc.).
