Finally. This first one's your run-of-the-mill third-person action game trailer:
But this one is far more interesting. It shows the player basically clearing a big swath of a level without ever firing a shot - everything is accomplished through squad commands, and a single levitation power used by the player-character.
They've clearly taken a lot of cues from Enemy Unknown, here, from the enemy names to the shield symbol that appears when you direct your units to move into cover to the percentage your units have to hit their target.
...which kinda' raises the question - how is this an improvement over Enemy Unknown, again?
