I loveth the alieensssesess.

This is ridiculous.
The trailer doesnt even look remotely anime, and if i'm wrong it's Pre-Rendered and not even made in the game engine.
However, those soldiers do look like samurais, maybe that will be a new soldier class like the ODST's in Halo 2.
They could have like superspeed and strength and they should be able to fly and shoot X-rays out their eyes.
