Everyone is anticipating on Titanfall though. I've never played it, but I know that mechs use a giant hand-held firearms (Unlike in Hawken, where mechs have built-in weapons on their arms) and that people can play as human pilots or "Titans". It's also obvious that the concept is completely different from other FPS.
The main similarity of both is that it's got mechs, but I think both has got different gameplays than each other. What do you think is better?
