Macworld UK: "Let's face it: any game where you kill zombies has its merits. Enter Aim for the Brain, a quick, fun title for the iPhone and iPod touch developed in conjunction with Westlake Interactive and PerfectDork Studios.
The title sort of explains it all. Open the game, choose one of three levels ("Alleyway". "Cemetery" or "Hospital"), choose a difficulty level ("Easy", "Normal" or "Hard") and begin shooting zombies as they duck out behind doorways, sewer grates, headstones, hallways, ceiling vents, etc."
