All upgrades of my RPG mod [ part of the FPS / TPS / RPG / RTS Mod ] have a visual release. New 3d model of the Hero unit with some 3d models of each upgrade. You can select one of three types of armor [ Marine, Marauder or Ghost ]. Each armor has unique ability [ Marine - StimPack, Marauder - Heavy armor and Ghost - Cloacking field ]. Also you can select one of 6 types of weapon. 3 Heavy weapons [ H-Flamer, H-Minigun, H-Rocket Launcher ] and 3 simple types of weapon with combination between them [ Chaingun with Flamer, or Rocket Launcher with Chaingun etc. ]. Last thing - one of three Jim Raynor's abilities [ Plasma Shot, Grenade or Slowing Field ].
