Ben 10 Aliens Defense

You control Ben Tennyson, positioned on a path the aliens march along. Your job is to stop waves of them from reaching and destroying a village. You move Ben left and right with the arrow keys, and you fire his Omnitrix-powered weapons at the approaching enemies. The game lets you switch between a few different guns, each with its own rate of fire and power, which you need to do as the waves get tougher and include different alien types. The pace picks up steadily, and it can get quite frantic trying to cover both sides of the screen later on. It feels like a race against the clock, managing your position and firepower to hold the line.
