Base Invaders is basically a different take on the popular 'defend the base' strategy game, developed by Seventh Sigma as another DigiPen project. Your objective is to repel enemy waves by building walls and placing elaborate traps around your tower.
There's a proper tutorial to help new users familiarize themselves with the controls, and each level introduces a new weapon or two instead of offering the entire selection immediately at the start and baffling players in the process.
Much like Dungeon Keeper, you can pick up the Invaders and throw them to inflict damage as well. The game includes a challenge mode and the excellent Invaderpedia, which offers inside information on every enemy type.
