Microsoft has released R-Type Dimensions on the Xbox LIVE Arcade today combining the classics, R-Type and R-Type II. You can play the game in the original 2D or brand new 3D graphics, and switch back and forth whenever you feel like doing so. Classic and Infinite modes can be played solo or multiplayer missions over Xbox LIVE or locally.
R-Type Dimensions is now available for 1200 Microsoft Points.
