When most gamers think about the numerous genres present on the Nintendo DS, “first-person shooter” probably doesn’t immediately spring to mind. Puzzlers, role-playing games, platformers, tactics games, action games, and plenty of casual fare can be found in abundance, but the shooters on that particular handheld are few and far between. Despite the challenges the touch screen and limited graphical capabilities present to developers of that genre, shooters like Metroid Prime: Hunters and Dementium: The Ward have proven that it can be done. C.O.R.E., a first-person shooter developed by NoWay Studio, goes the opposite way, making me wonder why anyone would ever want to play a shooter this headache-inducing on the DS.
