About

Lethal Extraction

Read full description

Descend into the unknown. Lethal Extraction is a first-person, co-op extraction horror where you and your squad breach procedurally generated zones, grab rare resources, and race the clock to extract alive. You are a Space Runner working for the Space Guild. Your mission is simple on paper: close the Breach, recover what’s valuable, and avoid the anomalies that hunt the dark. Silence is strategy. Team up with friends, keep formation, and hold your nerve while danger moves just out of sight. 〓Procedural expeditions, unpredictable runs〓 Every descent feels fresh. Everything changes: structures, routes, encounters, and pressure shift every time. 〓High-stakes extraction tension〓 Fail to extract and you lose what you carried. One more room can mean a bigger haul… or a clean wipe. 〓Cross-platform co-op + proximity voice〓 Play together on all supported devices. Proximity voice creates memorable and funny moments with your squad, and at the same time it builds up tension when you’re split… and when you’re not alone. Remember: your friends are not the only ones who can hear you! 〓Horror built for immersion〓 Atmospheric 3D retro style visuals, fog-shrouded corridors, and distorted moments turn exploration into paranoia. 〓Creatures + hazards with personality〓 Each threat behaves differently. Survival comes from reading patterns, reacting fast, and knowing when to disappear. Every entity has its own features and weaknesses to exploit. 〓Hub, progression & achievements〓 Return to your ship between runs to manage resources, track achievements, organize with your team, and prep your next descent. If you want multiplayer dread, co-op pressure with friends, and adventure wrapped in fear—Lethal Extraction delivers extraction horror on mobile with a style of its own.
