Space Invaders Extreme 2

Space Invaders Extreme 2 is a fixed shooter game, which was developed by Taito Corporation for Square Enix and released on the Nintendo DS in 2009; it is the 11th, and 10th official, game in their Space Invaders series as well as the fourth one since 1995's Akkanvader. Unlike the original Space Invaders Extreme, it never made it to Sony PlayStation Portable, Xbox 360 and Microsoft Windows, which meant it never gained the ability to let up to either three or four players play it simultaneously, and after the real-time strategy-based gameplay of its immediate predecessor, Space Invaders Get Even (where the player controlled one of the invaders' UFOs), it marks the series' return to its roots.
