Here are my impressions
campaign:
- it's fun and kinda open ended in that you don't have a linear mission path, you can choose which missions to play
- basic gameplay in the 6 or 7 missions i played is just kill the enemies. it's fun enough
- you can choose one out of several different autobots or decepticons (depending on which campaign you picked) for a mission. it certainly helps make it a little less repetitive because you can try different characters and use the different special attacks and abilities
- there's a lot of unlockable content. I just unlocked an episode of the G1 show called Dinobots
- there's a nice upgrade system (some include: max health, turbo recharge rate for car, weapon overheat rate, etc...there's like 15 of them). You use energon you get from mission to upgrade
- story is non-existent...i guess that's why you watch the movie. there are no cutscenes save for the intro i guess
multi-player:
- these are the modes: deathmatch, team deathmatch, battle for the shards (multiple flag CTF), control points, and another one that's like a guardian mode (each side has one, optimus or megatron)
- it's pretty fun and varied due to how you can choose characters that can fly, drive, helicopter, hover, etc. and all have different attacks and special abilities
- no lag at all for ps3 version, there weren't that many people online but i did get to play a couple full 8 player TDM that were fun
- no progression system or exp or anything like that...it's just the 5 modes.
overall, a pretty solid package for a movie game. I give it a 7.5
