I.T. Kid

Unleash massive armies against your opponent. The fifth and final entry scales the series up again -- the biggest armies of the five, on both sides of the field -- and keeps everything the earlier games built: the gold you spend on units, the hero you level between stages, and the enemy tower at the end of the push. Its own title screen carries the buttons for all four games before it, which is the series' own statement of how it fits together. CrazyMonkeyGames published it on 20 March 2008, with nearly half a million players on its own counter by then.
