Engine Heart is a game about little robots. When the humans were around, nobody paid any attention to them, but now that the humans are gone, the robots are on their own in a world that's falling apart.

Buildings are crumbling! Factories churn out disposable goods that continue to pack over-full stores, and everywhere our robots are desperately trying to obey the mandates of their programming.

A smattering of bodiless artificial intelligences - leftover servants given dominion over minute tasks - feud amongst each other, some proclaiming themselves as rightful rulers over all other AIs, some merely acting in their own alien interests. These powerful ghosts tower over the intellects of the robots, and consider them little more than spare parts or hapless, reprogrammed emissaries.

Rough societies have formed around the allocation of dwindling resources can be found wherever the robots gather, both within the petty kingdoms of the AIs or in the wilderness of ruined towns.

You have risen above the death-spiral that plagues so many of your kind, but now you must navigate the treacherous leavings of humanity, the machinations of murderous robots, and the walls at the edge of your own programming.

For even though the humans are gone, you must carry on.
