The wait for Halo Fireteam Raven is almost over, with the game now available at one Dave & Busters location and soon rolling out to the others.

We have confirmed that it is presently at the Rosemont, IL D&B location, which is where it appears that this picture was taken for this tweet;

You also have this video showing all of the cutscenes captured from a test unit:
The game has about 45 minutes of gameplay which is about 20 minutes longer than most light-gun shooters; if you really don’t mind spoilers then this video shows the whole thing.
For something shorter, Raw Thrills also released this new trailer to promote the game for the Summer Dave & Busters release (as a reminder, other locations out there will have access to it around September). It has not been confirmed exactly when that will take place but given that the Summer is upon us, it should be happening any time now (given that the location test unit will be finalized in July, we can guess to look for it at other D&Bs around then).
