Mass Effect Galaxy is a screen-by-screen shooter that will remind old school gamers right away of the classic arcade game Smash TV. Each screen is full of enemies that must be dispatched before an exit to the next area aboard the massive Citadel space station opens. To move Jacob, you tilt the iPhone in the direction you want to run. To target an enemy, you tap it. Now, Jacob will auto-target that enemy until it is either dead or a new foe is tapped. Jacob automatically fires his normal weapon, but you have a handful of special attacks, access by touching virtual buttons on the right side of the screen.
