If i recall correctly, they have Doom of Aliens, Space Tanks, House of Heroes and i think Dragon Knights or something. I have played house of Heroes, it's quite nice 3d RPG shooting game,not so fancy but not so bad either.
Among those you've mentioned above, they also have a game named Wrath of War. It's one of the first projects that Mobs Arts developed in a U3D strategy game,which was also independently developed by them for over 2 years. It's in high quality and it has a heavy brain-burning gameplay,perfectly designed to meet the requirement of the strategy game market.
