UnderDoor's eerie action and puzzles

Seven tense games from UnderDoor that let you explore strange places, solve spatial puzzles, and survive monsters and heavy fire.

If you are drawn to tense spaces where you have to keep moving and think fast, these seven games from UnderDoor will feel familiar. Fallen Depths, 飢界 and 傀儡禁域 all center on exploring hostile floors or worlds and staying alive against strange creatures while you search for a way out or forward. Around that core you can also test spatial thinking in PARALLEL RIFT, follow a slow unsettling trail in The Contact, chase points in 傀儡の宿 - Kairai Inn -, or handle dense fire in CORPSE58.
