For a limited time grab The Flame in the Flood for free from the Humble Bundle store.
From the Store description:
A rogue-lite river journey through the backwaters of a forgotten post-societal America. Forage, craft, evade predators.
From the Art Director of BioShock and a team of veterans of the BioShock, Halo, Guitar Hero and Rock Band series comes The Flame in the Flood.
Travel by foot and by raft down a procedurally-generated river as you scrounge for resources, craft tools, remedy afflictions, evade the vicious wildlife, and most importantly, stay ahead of the coming rains.
