Armored Core 4 (Playstation 3, 2007)

This is a great game if you're into mech battles(Which are big building sized robots). I've played all of the Armored Core games and this is by far the best due to the fix in the flight and balance. It's easier to maintain your flight time while attacking your enemies below, even if you prefer heavy mechs. The game was a bit harder than the first three, but it was challenging! An all around fun game.
