I'll start off by saying that Unit 13 is fun, but flawed. Gameplay wise it will have you hooked, at first, then you'll grow tired of the same maps that you will have to grind so you can progress. The cover mechanics are fairly good with a couple glitches, but not enough to get you killed. The in-game physics are nice, nothing to complain about except that every once and a while the enemies will be blown 50 feet in the air. Graphically, the game looks very nice on the vita's screen, thought at first you may find that you have some difficulty navigating the levels as some of the colors blend, but with the screen brightness all the way up it's not to bad. The glitches are not game breaking and are even a little funny, as some AI will get stuck doing the same animations over and over again, or they will run into walls, but overall this is a great game that the multiplayer gives more play value to.
yes: I recommend this product
