Though there are hundreds of different ways that you can personalize your character, the class system in Defiance is a bit peculiar. Instead of choosing a class, as is the case in most MMOs, you can develop your character's concept little by little as you select new abilities.
In Defiance you progress as you manage to defeat enemies and, above all, as you complete different 'quests' alongside other players. You can play Defiance on your own and have fun, but the best thing about it is precisely the things that it allows you to do when you are playing along with other players.
As the Defiance world is absolutely huge, you can travel through it on foot or using one of the many vehicles that you can find there. Not only can you move around using these vehicles, but you can also fight using them, if need be.
Defiance is a remarkable third person action MMO. It was a paid game for a year, but it is now available for free. It's a true gift for anyone who is looking for a new adventure filled to the brim with shooting, explosions, aliens and action.
The minimum requirements to play the game are: Intel Core 2 Duo 2.0 GHz, 2 GB RAM, 512MB graphics card (NVIDIA GeForce 8600, ATI Radeon HD 2900, or Intel HD 4000), 15 GB of hard drive space.
