Travel in the genre of lightweight bagels to the deaf river plants of a forgotten America, forever lost its civilization. You will have to look for food, make tools and escape from wild predators.

The Flame in the Flood was developed by the main artist BioShock and a team of veteran game developers BioShock, Halo, Guitar Hero and Rock Band.

Travel on foot and on a raft along a procedurally created river, look for supplies, master tools, cure diseases, avoid aggressive representatives of the local fauna and most importantly, act to anticipate coming down rains.
