Earth Defenders: a game where you control a slow invasion fleet descending towards a planet defended by one ridiculously manoeuvrable ship that hides behind asteroids and picks off your outriders one by one.

Angry Plumber: you're a gorilla on a date with your human girlfriend at the top of a half-constructed building. A plumber is climbing the scaffolding to hit you with his wrench and kidnap your girlfriend. All you have to defend yourself with is this pile of barrels.
