A game I wanted to try to ID About a year ago I saw a preview for a Console FPS game that involved shooting at robots that had aliens inside them or over them the aliens worked the robots like puppets and the main weapon in the game was endlessly customisable but was not swappable. the demo in question had the player coloring the gun mad colours. and you could swap parts you collected to give it sniper extensions or a grenade launcher etc... Anyone know what that game was and if it ever came out or not ? Oh sorry I just realised this is in the wrong place it's supposed to be in general Videogames perhaps it can be moved please.
I haven't played either of these games so I could be way off, but what you described sounds like what I've heard about Section 8 and/or Vanquish.
This isnt a transformers game it needs to be moved back... Still I think I know of the game your talking about but I cant remeber the name...
