Purgatory (itch) (immortalinc)
About
Purgatory is a first-person game that begins shortly after an earthquake. The player regains consciousness inside the character's workplace, Psion Labs, which specializes in experimental technologies. The building is on fire and quickly filling with smoke, but the exits are blocked. The player finds the Sonic Splinter - an experimental device that uses sound waves to quickly fragment solid materials. The player must use the device to escape the burning building before time runs out.
