What players say

68% of 3,197 reviews are positive · 70% of 10 in the last 30 days

Players praise the underground setting, story, and factory-building depth. Many criticize changes made for the full release, calling later objectives repetitive and the ending rushed. They also report bugs, worsening performance as factories grow, and lag in later co-op play.
