Monster Energy has sealed a deal with Activision to produce specially-branded energy drinks as a means of endorsing Call of Duty: Modern Warfare 2. However, Monster’s promotion is also valuable intel, as it hints at the due date of the game’s first DLC package.

Purchasers of these themed cans will be automatically entered into a draw to win Modern Warfare 2-related prizes, including one of 5,000 codes for a free download of Map Pack 1 – which, if the ‘Monster Assault Energy’ four-pack's packaging is anything to go by, is planned for release in Spring 2010.

We imagine this is the first of the two Map Packs Infinity Ward promised back in August. Expect a sudden outbreak of sugar-loaded, over-caffeinated gamers in the coming months.
