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. Built for players who seek a true survival challenge, it features advanced survival mechanics, realistic visuals, and unforgiving combat against both mutant creatures and hostile human factions. Manage hunger, radiation, temperature, and stamina as you scavenge, craft, and adapt to a collapsing ecosystem. Engage in tactical PvE and PvP encounters where precision, awareness, and strategy are the keys to survival. In this world shaped by nuclear fallout and desperation, every choice defines who you become. Remember, you have a choice.
