Total Chaos is a relentless survival horror experience from Trigger Happy Interactive (creator of Turbo Overkill) and Apogee Entertainment. Washed ashore on Fort Oasis, a long-abandoned mining colony swallowed by decay, players must scavenge for supplies, craft makeshift weapons, and navigate a world where hallucinations warp reality and unspeakable horrors lurk in the shadows. With dynamic AI-driven enemies, a Madness system that distorts perception, and a brutal fight for survival, Total Chaos pushes the boundaries of psychological horror. Every bullet counts, every wound matters, and your own mind may be your worst enemy. Prepare to descend into madness. Total Chaos launches in 2025 on PC via Steam, with an optional VR mode for those brave enough to step inside the nightmare.
