Fatboy is the UEF land experamental from SC:FA. It features 4 long range battleship cannons, airpads, some lmgs, torpedos for underwater, an area shield, and a good mobile factory to boot. As to if it fits in this game, we have mobile artillary in the Merlin/catapult, and everyone would say that dealing massive damage from range is not a good fit for this game I think. so airpads are on reef, sea only, funnelweb has shield, land only, we have long range damage with merlin, but I feel the damage is delt different, and the mobile factory in an athena or few. Striders in this game are often compared to experimentals in SC:FA, but they definately feel different to me, a lot closer to general units in cost and effectiveness.
