Batman: Arkham City is available today. You can no longer get all those unlockable costumes that came only came with pre-orders. Arkham City was pretty notorious for offering retailer-specific costumes, but there will certainly be a way to purchase all of them in due time. In fact, you can get the Batman Beyond skin today if you purchase a NOS energy drink. Who knows, it may come in handy by keeping you energized while you complete all those Riddler challenges.

Gamers most likely know the name Harcos because of the companys various, gaming-related energy drinks. For example, there’s the Health Energy Potion, the Mana Energy Potion and, my personal favorite, Zombie Blood. The company is known for capitalizing on fads, so it’s not surprising that it’s latest product cashes in on the Charlie Sheen whirlwind tour. Time to bring out the Tiger Blood…

Harcos is an energy drink manufacturer that caters mainly to gamers, teenagers and pop-culture fans with a series of whimsical energy drinks (and powders!) that provide energy in an array of flavors and eye-catching containers. Their latest product is Zombie Blood, a neon-green, lime-flavored, energy potion packaged in a blood bag that’s designed to give drinkers a four hour energy boost.

After getting a chance to test it out, I can easily say Zombie Blood is the tastiest, most refreshing and most novel energy drink available. I can’t believe Harcos didn’t tap zombies for their sweet nectar sooner…

Drinking and gaming. We saw it happen with Halo and World of Warcraftand now a beverage company is trying to help juice up Call of Duty: Modern Warfare 2. Monster Energy drink has teamed up with Activision for a cross-promotional effort that the companies hope will help keep gamers from passing out during MW2 marathon gaming sessions.

Even more interesting are the promises on the drinks’ packaging which indicate that Monster will give away MW2games which will be available November 11, 2009 for PS3, Xbox 360 and Windows, as well as downloadable content (DLC), indicated to be available Spring 2010.

Monster may have jumped the gun because Infinity Ward’s Community Manager Robert Bowling said production on DLC hasn’t even started yet.
