The newest PV showed some more co-op vs BETA. So far only the Grappler-class BETA and small Laser-class BETA is seen in the game. New updates includes more dynamic camera angles, Laser-class BETA warnings, better friendly AI and Japanese HUD (even though the TSF is F-15 Strike Eagle LOL).
So far the game looked great, hopefully we'll see more videos before the release.
