This game deserves more than a 7.5. I had a lot of fun playing it and it was funny to. this game is sure to be a hit.
controls: The controls are pretty simple. you can learn the control in 15 minutes. The only bad thing is to aim you need to move the right anolog stick up, down, right, and left to point the cursor. most people aren't left handed and may be uncomfortable.
gameplay:The gameplay is also very simple. Most of the time your just going to be jumping around shooting pedestrians with your disinigrater gun. After the missions you can freely rome the invasion site in a grand theft auto way, killing people and completing side missions collecting dna along the way. you could also go to poxes lab to buy upgrades with dna.
graphics: This is where the major problem comes in. Usually the buildings pop up when you get closer. Even when your in your sauser buildings suddenly pop up. But other than that the graphics are pretty good.
how it compares to the rest of the series: Destroy all humans is so far one of the best games in its series, and makes a good first appeal.
All in all destroy all humans is a great great game, but but may be to simple. If you want a challenging game you may not want to get it.
