Bit.Trip: Beat has been revealed in Bit.Trip: Core, GameSpot reports. If you thought it was tough keeping track of rogue pixels assaulting you from one direction, then you're going to have an even tougher time with Core, as the player must now defend against attacking pixels from four different directions.
Another big change comes in the controls department. The first game featured motion-based controls, but in Core you're stuck in the middle of the screen, pushing directions on the d-pad to shine a beam of light toward rushing pixels. It's essentially the same type of gameplay, combining rhythm and shmup elements, so if you liked Bit.Trip: Beat, then you'll likely find value in this. The game also adds a progress meter showing you how far you've made it into a stage, as well as a screen clearing ability that will hopefully ease the experience up a bit.
Bit.Trip: Core is due for release on WiiWare sometime this summer.
