DarkFire

The lights went out across the city, and whatever crawled in to replace them isn't interested in a clean kill. You hold one rooftop with one rifle, watching a corruption gauge fill every time something gets a hand on you before the dark climbs the wall.

That gauge is the whole threat: stay sharp enough to keep aiming and you're fine, get grabbed too often and the game shows you exactly what "corrupted" means, in pixel-art capture sequences triggered mid-fight.

You don't move. You aim, shoot, reload, and swap gear across twenty waves split into three acts, each one ending in a boss that wants your last mag. Death resets the run but keeps whatever permanent upgrades you scraped together, so the next attempt starts a little less doomed than the last.
