It looks really similar to the last Transformers game on Wii... I didn`t like that game, simply because it was boring.
I don`t know if choosing cover is enough to make an already really boring gameplay-style fresh!? I`m skeptical...
I also think it is a shame, that they didn`t wanted to make a proper third-person-game, since I think the Wiimote-Nunchuck controls would fit it well, similar to rogue trooper just with the updates made on IR-controls in the meantime (such as boundary-boxes, turning-speed, etc).
