What players say

81% of 55,433 reviews are positive · 83% of 3,780 in the last 30 days

Players most often praise the Soviet retro-futurist setting, detailed environments, visual design, and music. The most common complaint is that rapidly respawning and self-repairing enemies make the semi-open overworld tedious to explore; players also criticize repetitive combat, resource collection, and uneven writing.
