Tiberian Sun Factory - for new unit graphics. Ultima Mod adds hundreds of new vehicles, infantry, aircraft, ships, buildings, weapons, and superweapons to your inventory all of which have either new graphics or modified Tiberian Sun ones. With a greater emphasis being put on mobility, portable meteor controllers, exploding gas tankers, ion cannon firing units and black hole makers are common sights. But the best improvement has to be the addition of naval units. Well now you can do it in Tiberian Sun with huge tripple-barrelled cruisers for GDI, that can knock a construction yard out in two shots, and long ranged missile subs for NOD that'll sneak in undetected and deliver their payload.
Land based assaults are far from boring, though.
Resurrection of the old suicide philosophy now means that you can also employ backhand tactics using the provided Ion Demo Trucks and Demo Chem Tankers that'll leave the enemy base full of either green gas cloud mahem or hundreds of pretty ionic beams of destruction. The aircraft are no let-down either. Well the Scout Droid should sort it out. Build one and it'll automatically seek out the enemy base and show it to you. New aircraft let you EMP the enemy from the air to neutralise their defences, so that big attack of yours doesn't get shot to pieces, and monsters of the sky return - gigantic airships that drop round after round of deadly bombs aswell as robotic droids that deliver limitless waves of sonic destruction.
