Touch the Dead review at 1-up.
"Light-gun games are a dying genre nowadays, but that hasn't stopped the DS from poorly resurrecting a few random titles. Touch the Dead -- no relation to the classic Sega shooter The House of the Dead -- is one of the most literal game titles you'll find. You, well, touch the dead...a lot.
But groping ghoulies with the stylus just isn't as much fun as blasting holes in 'em with a pistol. The simple light-gun mechanic worked in the arcade because of the visceral feeling you got from blowing the brains out of lumbering lunatics; trying to translate that feeling to a small plastic pen isn't as exciting. It didn't work with Point Blank DS, and it certainly doesn't work with Touch the Dead.
As mediocre as Point Blank DS was, at least it had variety, something you won't find in this rotten game. Plus, the game's zombies are genuinely ugly, and not ugly in an I-can't-wait-to-kill-these-monsters kind of way, but in a very literal what-the-hell-am-I-supposed-to-be-tapping kind of way. Yeah, I know the DS is no portable powerhouse, but the graphics don't need to be this terrible. It's not just the enemies, either. The environments are so bloody boring -- a no-no for an on-rails game like this."
