Bethesda has released a new trailer for the third DLC expansion for Fallout 3, Broken Steel, due out for Xbox 360 tomorrow, May 5. We strongly suggest that you don’t play the video if you haven’t finished the game, since it spoils something big (and metal). If you’ve finished the game (or just don’t care), by all means, play away. But precede with caution.

The trailer provides a quick glimpse of how the add-on will continue on from an ending that was designed to be the end along with plenty of Brotherhood vs. Enclave laser-blastin’ action. Oh, and that something big being generally awesome. In fact, just watching the footage will make the next 12 hours or so before the DCL pack goes live that much harder.
