While unconventional, zip lines provide an excellent opportunity to brush up on acquiring and eliminating moving targets. Oh, and I suppose they're also a fast form of transportation.

Video Blips:

• Attend well to the advice of Treyarch's development team as they describe the new maps of Call of Duty: Black Ops's “First Strike” downloadable content. Germany's Berlin Wall would have been a lot less political and a lot more chaotic if it actually contained automated chainguns.

Continue after the break for Epic Games' quirky explanation of the weapons and modes in Bulletstorm, the introduction of Mortal Kombat's vile succubus Mileena, and Yakuza: Of the End's conspicuous symptoms of zombie tie-in mania.

• Epic Games' Cliff Bleszinski, Tanya Jessen, and John Liberto breaks down the modes and weapons of Bulletstorm. Giving the minigun the colorful description of “an extension of [protagonist] Grayson's penis” simultaneously fits the game's lurid theme and makes me want to reach for another weapon in disgust.

• Mileena's home is the flesh-pits created by Shang Tsung, but her bloodlust is a perfect match for the arenas of Mortal Kombat. Even the cameraman isn't safe from Mileena's...er, advances.

• Even Japan's most notorious criminal syndicate isn't safe from the zombie horde in Yakuza: Of the End. At least Mr. Machine Gun Arm can be put to use without looking ridiculously out of place. [GameTrailers]
