A package from Activision arrived today, and while it sounded like there was liquid inside, we weren't prepared for this -- Call of Duty: Modern Warfare 2 branded Monster Energy drinks! 

The box for four-pack appears to confirm that it's planned for a Spring 2010 release. As this is the first we've heard of this, we checked in with Activision who could only tell us that more details would be coming soon. 

Also available as prizes will be copies of Call of Duty: Modern Warfare 2 Hardened Edition; Modern Warfare 2 themes for Xbox 360 and PlayStation 3; and, in case you're not amped up enough, more energy drinks. 

Sam's Club will exclusively be offering a six-pack of the drink, which will grant access to something called the "Call of Duty: Modern Warfare 2 Combat Training Experience." According to Activision, this is "exclusive, online event at Infinity Ward that will be an in depth look at Call of Duty: Modern Warfare 2 this November."

Check the gallery to see what you should be looking for in stores, and hit the jump to read the most hilarious Call of Duty-related copy (which appears on the side of the can) ever. 

The next evolution in gaming is coming... Modern Warfare 2. If you've ever played Call of Duty you know what we're talking about. Creator Infinity Ward hooked us up with an advance copy of MW2 and we were so stoked on the game we put it on our can. Grab a Monster Assault and prepare to wage an all out assault against the many faces of modern warfare.
