Oh man, that game was fantastic... shame that it got shut down. But really, for me personally most of it was actually pretty easy, except for that one first insecticon boss fight with grimlock, that was ROUGH. The final boss fight with megatron might also be hard to start with, but really you have to make liberal use of the shield and always keep attacking him up front rather than far away. I only died most of the time through lag and crappy rifle damage. I was playing on PC though, so I think I had it easier.
