INFRA puts you into the boots of a structural analyst on a routine mission. Quickly though, your task turns into a fight for survival, all caused by deep-rooted schemes of the past. Your tools are simple: your camera and the wits to navigate a labyrinth of debris.

“I thought this would be just a normal walking simulator but ♥♥♥♥♥♥♥♥ I was wrong. There's so much depth on how far the corruption goes, and its consequences. If I ever get amnesia, I would definitely play this again.”
“Fun for a long term play experience and with lots of secrets and achievements so it never gets boring.”
