Engine Heart
The time of the humans has passed.
All that you were built for is no more.
But you and your kind endure.
Engine Heart is a role-playing game set in a post-human world. All the players are small service robots that have managed to survive and continue functioning.
The game runs on a heavily-modified version of the ArtifIce drone rules. All checks are made using d10s, either singly or (more commonly) in dice pools.
