About Backrooms: Facility Unknown
Backrooms: Facility Unknown is a co-op survival horror game developed by Triple E Games and released on October 25, 2025. Set in a large, eerie facility, it blends exploration with tense resource management. Players navigate the environment solo or with up to three friends, balancing job objectives like collecting items or solving puzzles while evading threats. The PC-only title focuses on asymmetrical teamwork, with mechanics that prioritize stealth and strategy. Though the core loop is straightforward, the game leans into claustrophobic atmosphere and unpredictable encounters. Community tags label it as “strategic,” reflecting its focus on planning over pure action.
Gameplay
The gameplay revolves around slow, deliberate exploration. Players move through procedurally generated rooms, gathering supplies to craft tools and weapons. Each session lasts 45 minutes to an hour, with permadeath adding stakes. Enemies are silent but persistent, forcing players to balance aggression and caution. Co-op requires constant communication, splitting teams to cover more ground or pooling resources for tough sections. Controls are responsive but minimalistic, favoring keyboard/mouse precision for navigation. The “job” objectives shift between runs, from retrieving files to disabling security systems. While the strategic layer is strong, repetition creeps in during solo play.
What Players Think
Critic reception is mixed at 72%, with users averaging 7.8/10. Average playtime is 11 hours, but only 23% complete the game, suggesting high difficulty or engagement drop-off. The “strategic” tag has one vote, hinting at niche appeal. Community moods lean tense but divided: one review calls it “a masterclass in survival tension,” while another calls it “repetitive.” Co-op players praise teamwork mechanics, but solo runs are criticized for dragging. Achievements are present, though only 42% of players earn at least one. Most complaints focus on recycled enemy encounters and underdeveloped lore.
PlayPile's Take
Backrooms: Facility Unknown is worth playing for fans of co-op survival mechanics and those who enjoy planning over action. At $29.99, it’s a mid-tier purchase with moderate replay value. The 42% achievement completion rate shows it’s achievable but not overly grindy. While solo play falters due to repetition, the co-op mode justifies the price for groups. Best for players who thrive in high-pressure, resource-scarce environments. Skip if you prefer fast-paced horror or open-ended exploration.
