Yahoo is exclusively hosting the first proper trailer for Indiana Jones and the Staff of Kings. The video features developer interviews, clips from all four films, shots of people actually playing the game, and of course the first in-game footage LucasArts have released since 2006.
The game looks significantly better than the first Wii screenshots would have had us believe, and just to emphasize the point there are new better-looking screenshots available too.
Of particular note in the video is a brief shot of the game's co-op mode, which features a different campaign to the main story mode and seems to feature Indy and Sean Connery's Henry Jones Snr. as the two playable characters.
