GIZORAMA - What happens when you take a first person shooter like Serious Sam and mix a little Contra in? You get Serious Sam Double D XXL from Mommy’s Best Games. XXL is a console port of the PC game Serious Sam Double D and adds local co-op with more missions, challenges, enemies, and upgrades. MBG is best known for Nathan Fouts and his Xbox Indie Game, Weapon of Choice. It is easy to see that DD draws influence with Fouts’ previous works while keeping the Serious Sam feel to it.
