You can now download the Lost Planet Map Pack 1 on the Xbox Live Marketplace. For the hefty price of 400 Microsoft Points ($5), you get 2 new maps, “Island 902″ and “Radar Field”. The new maps can only be played on Xbox Live, so your hopes of using them in offline multiplayer have been dashed.

It’s a pretty steep price of just 2 maps. Most other map packs have been 400 MS Points for about 4-5 maps, which seems pretty fair. But spending $5 to just get 2 new terrains is insane. I don’t think they’ll be selling a lot of these.
