The Nintendo DS may not be the most comfortable platform to play a first-person shooter on, but that doesn't stop developer NoWay from taking a shot. C.O.R.E. takes place beneath the surface of the earth in the Mojave Desert, where an underground research facility has been built. C.O.R.E. plays very much like other FPS games on the DS, and while you may find many similarities when comparing it to games like Moon, the fact that you can play C.O.R.E. with up to three players locally gives it a distinct advantage.
