I bought this yesterday in El-giganten for me and Malu. We started playing split-screen today, me as the robotic sniper with mutated pets, FL4K, and Malu as Amara, the many-armed siren. So far, it's both good and bad - the weapons are fun and varied, and the controls work fine, but when any players has menus open, which you're doing *all the time* in this game, the frame rate becomes unplayable unstable and bad. Hoping for a patch.
