Obscura

In Obscura the player experiences life in a mysterious city in an inglorious future. It is not allowed to be out at night. The official version of the government states that it is for their citizen's protection, in reality AI combat robots are tested at night, who fight everyone they encounter, so you better be home at dusk and if you do not have a home, you are on your own.

The player collects items, weapons and coins and fights against the AI enemies at night. Akari's score increases with every coin collected and eventually she might have enough coins to afford a home. Or maybe she will collect coins forever in hope that it will be enough some day ...
