New DLC is on the way this week for the Xbox Live Arcade version of Space Invaders Extreme. This note from the publisher says about all there is to say about it.
Space Invaders Extreme is coming out with new DLC tomorrow night, Wednesday, June 17, 2009. There will be three new stages, new enemies, and new bosses. Additionally, the expansion pack will contain two emulators of the original black-and-white Space Invaders and 8-bit color Space Invaders 2!
The pack will run you 240 Microsoft Points (or $3), and I hear tell the emulated original games will be standalone and not integrated with the core SIE gameplay. At any rate, I think this DLC is more about showing than telling, so here you go!
