With a full bucket of revolutionary MMO concepts, as well as fine-tuning existing MMO gameplay, this is the game to get.
The idea in the game is that aliens sent some sort of biological "contamination" down to Earth, mutating thousands of people and creating war between the pure Humans and the Mutants. The Humans create the Biomeks - near perfect soldiers that are designed to fight the Mutants. However, war goes on, with neither side taking the lead. The Humans, now branded together in the Hestia Company, build massive underground Arks to hide in. They try to cleanse the planet by unleashing massive biological/chemical/nuclear weapons on the surface of the Earth, creating a wasteland out of what used to be a great civilization.
As the name says, Auto Assault is a car combat game. You start out customizing every inch of your character and your car. After a brief but fun tutorial, you are able to explore the Auto Assault universe, traveling between Highways and completing missions. The nice thing is that you never have to "grind" to get XP. There are thousands of different missions, with different objectives, and they give much more XP then if you would be grinding.
The fully-destructible environment is a very nice feature. Everything from the buildings to the cars can be destroyed. The physics engine is amazing, and the graphics are pretty good too. What I really like is the music - it fits the Auto Assault universe perfectly.
There are only a few problems with the game, mostly with balance issues since the game is just released today. The interface doesn't feel very "snappy" and sometimes gets in your way in combat. Unfortunately, most other reviewers might give a low score because they didn't play the game very long. Believe me, the game starts out pretty boring, but as you near the end-game content, it is the best experience you could ever get. Don't believe people who give a bad score unless they have played for a long time.
Overall, Auto Assault stacks up among one of the top games. With new features and redefined concepts, Auto Assault is the game to get.
