About Protocol Zero
Protocol Zero is a hardcore, realism-driven survival game set somewhere in post-apocalyptic Europe after a global nuclear catastrophe. The world lies in ruins, cities abandoned, landscapes irradiated, and life twisted by mutation. Every choice defines who you become. Remember, you have a choice.
