Transformers: War for Cybertron

When you get to the tank before entering the gates, shoot the blue spot on his back. use the debris for cover (as they say in game) and blast the armor shell off of him. He will eventually fall.

When fighting zeta prime, avoid the orange squares on the ground (the pistons in the ceiling will come crashing down on it)

use the magma launcher to blow away the energon clones, then lay into the center ball as it opens. do this 4 times and it will enter the cutscene.
