Sega has announced that it will bring Megadrive titles Crack Down and ESWAT to Xbox Live Arcade.
To clear up the confusion, this is Crack Down, not Crackdown. Crack Down is a top down shooter that is swamped with onscreen menus and information, the action only taking place in a quarter of the screen. Hopefully the token 'enhanced graphics' means Sega will tidy the onscreen HUD up, lest our eyes shrivel up with information overload.
ESWAT: City Under Siege is a side-scrolling shooter that has you controlling some sort of flying-robot-man-thing with a rocket launcher. You're saving a city under siege, obviously, and there will probably be an end boss called Mr X (who's in command of "shadowy forces"). No release date for either game yet, sadly.
