Argggh, the aliens are coming! A new Command & Conquer 3 trailer showcases the Scrin, the insectoid extra-terrestrials joining the Nod versus GDI war party in the RTS sequel. Check out the battle carnage via our video player on the right - swarms of rank-and-file buzzer units that cut up enemies, death-dealing lasers... Nice.

And while it's not shown in the movie, just wait till you see the Scrin end-game unit, a massive mothership that takes up nearly all the screen - it's a bit like Red Alert 2's Soviet air unit the Kirov Airship. But with aliens in it and more futuristic.
