I.T. Kid

The first Thing-Thing: a lab experiment breaks out and shoots its way through the facility -- run, jump, and unload an absurd arsenal in the series' opening chapter. Weasel's original set the template the sequels followed: a side-scrolling run-and-gun with a stack of weapons, a comic undercurrent, and a body count. Kongregate's page counted 45,588 gameplays and 3,768 ratings by the end of 2008, and the series it started became one of the portal's biggest. Move with the arrow keys, aim and fire with the mouse, and switch weapons as the ammo runs dry.
