Shattered Haven

Shattered Haven is a survival puzzle adventure video game created and published by Arcen Games. The plot is set in a Lovecraftian post-apocalypse, where the player must navigate branching storylines to protect a small family from zombies (called "grays" in the game), limited resources, and impassible terrain. Each level is a fully contained puzzle, and the player must use only the resources contained in that level to complete the objective. (wikipedia.org)
