This was my first game for the PSP and whist I think a good amount of effort went into the game (the number of new maps is noteworthy), it is perhaps just a bit on the easy side. I think play could have been greatly improved with a control system that did not resolve so much around targetting. That said, the story mode is good, the Col Serra character in particualar is voiced well, and the cutscenes are fun to watch. The character customisation was a good idea, but was perhaps a bit limiting. The most improvements have been made to the space missions, with target-camera, heroes, and astroid bases being great additions. All in all, a great game for a while at least, and a great steeping point for the (hopefully) fully-fledged next installment. It would be nice to see some DLC, though.
