Fast-paced shooting action helps the Space Invaders series celebrate its 30th anniversary in style.
* New weapons and enemies make a 30 year-old formula feel fresh
* Local and online multiplayer is lots of fun
* Basic gameplay is easy to grasp, but has additional layers of depth
to appeal to skilled players.
* Single-player mode is far too short
* No online multiplayer or leaderboards in PSP version
* Lots of meaningless gauges and meters.
