This game comes out on Tuesday. I've been cautiously optamistic(sp?) about this one. It looks great but it is a transformers game after all, when have they ever made a good one of those? But after getting a brief chance to play the multiplayer demo on Xbox, I'm very excited and will be picking this up on tuesday. The multiplayer is divided into 4 classes (2 of which are playable in the demo).
The Scout (playable in demo) - Transforms into a speedy car, can cloak, and has weapons like shotguns, sniper rifles, a revolver and a charge up plasma cannon that probably does lots of damage when fully charged but I never hit anything with it.
The Scientist - This one transforms into a jet, and has abilities that heal and support the team. not in the demo so I can't say much more.
The Leader - This class as far as I can tell is based around Optimus. The leader transforms into a truck and has powers that buff the team and such. He can also ram people when in truck mode.
The Soldier (playable in demo) - Transforms into a tank. He has a hover power that I believe gives him a damage reduction bonus while doing it, and also has "whirlwind" power, in which he pulls out his giant ax and spins around for 10 or so seconds doing severe damage to anything he touches. He has rocket launchers and assault rifles and things like that.
All classes have other powers they can unlock as you rank up and they also have 3 perks ala call of duty.
Transforming is quick and easy do to with a click of the right thumbstick, and lets you get around quickly. While transformed you are more vulnerable, but all vehicle modes do have weapons, but that is mostly just used for harassment as they're not as powerful as your normal weapons. Health is different from your standard magical regenerating back to full health thing that most shooters do. Each class has a different amount of "health boxes", (4 for scout, 7 for soldier, probably 5 and 6 for the other two) and once you lose all of box, it won't regenerate (So if you lose 2 and half boxes, you'll regain half the box, but the other two wont). However there are health pick ups scattered around the map that will bring you back to full.
This game looks very promising, But I don't think that I will be getting the PC version, as it's by activision, and there has been no word on anything about the pc version, so I fear we have another MW2 on our hands in that regard.
