Dead Trigger is a first-person shooter that was released over the weekend on iOS and Android. The draw here is that, at least on a retina display (iPad included) it looks amazing.
Shame it doesn't play that way. Dead Trigger suffers the same issues any other first-person shooter has on a phone; namely, that there just isn't the input to move, aim and shoot at the same time, so you're always having to give at least one of them up.
On the plus side... it looks great. It's out now on iOS and will be out later today on Android.
