Bailout, Storm and Salvage are their names, and they'll be joining Call of Duty 4 favourites Crash and Overgrown as part of the Stimulus Pack.
New maps are always welcome, but if you're worried about confusing new locations wreaking havoc on your precious kill/death ratio, the folks at Inside Xbox have provided a useful video walkthrough that guides you through the Stimulus Pack's three new maps.
Expect Infinity Ward to dish out a bevy of additional details over the coming days, but for those wanting to an early glimpse, check out the Inside Xbox video below.
The Stimulus Pack will be available to Xbox 360 users via Xbox Live Marketplace on March 30th and is expected to make its way to other platforms at a later date.
To coincide with the Xbox 360 launch, Infinity Ward will be kicking off a worldwide Double XP weekend for Modern Warfare 2, taking place from April 2nd to April 5th. Time to finally take the plunge and Prestige, perhaps?
