In capitalist America, we bear arms In soviet Russia, we arm bears
Rise of the Martian Bear dlc give players a lot more weapons to customise your trench(about x2 more), added 1~2 type of mech chassis, tonnes of marines costume to unlock and 1 Mars campaign (5 missions) and 2 survival mode (swamp & settlement).
the dlc added several more tubes type that are alot more tougher than the original. Technically players are playing on the 4th campaign, and are expected to be level 10 and above.
Price at 400msp ($5), provide huge content to extend the longevity of the game. 4th campaign itself clock about 4hrs. I high recommend players to get this dlc if you already own trenched/iron brigade. However, if iron brigade does not interest you, this dlc will not.
