Great way to promote the Ageia PhysX hardware! (but without it's pretty much a loss of time...)
The game in it's self is not to hard to master and is existing of 5 different maps, which only 2 are playble if you don't have the right hardware. Which isn't all to strange since this is after all a FREE-promotinal game for just that hardware.
Me myself is not a owner of such thing and therefore finds it difficult to run the game since it has a tendency to stutter/lagg even if my computer is somewhat classified as "High-end".
The graphics are sharp and just right for this kind of game, the character designs are intressenting and gives all three classes a special look as well as their special power.
The three classes are the Black Ops, Guardians and Bishop. The black ops are the closest thing you get to a normal foot-soldier as they dont make any extreme leaps or hoover. They use firearms as their first attack but do like the others possess psyhcic abilities and can pick up and send a box flying into a near enenmy if so is deemed necessary, they are also the only once that can use vechiles. the Guardians are more cybernetic/robot like and uses dual Firearms as well as some pshycic abilities just as well as they can plunge several feets up into the air and land where ever. the Bishop is a soley psyhcic based fighter as hoovers trough the air and pick almost how many loose objects she would like and hurl them at and increble rate into enemys just as well as she might pick someone up and crush that one.
These add parts of what's so special in this small game, they make for different gameplay and adds to the already fast paced action.
However, I would not necessarily recommend one to try this unless you have the right hardware.
