You must/should have English version of game! T.U.S.T.K. 2. (replaced by Switch) is a small program. With this program you can Load maps, Swap PAK and INI Files (Original Game PAK with Hacked/Edited PAK), Quickly start multiplayer, And Mod Manager to load mods. InstaLauncher is a small program, works like T.U.S.T.K. but every time you start it restores original files, starts a game, swaps INI files with modded ==Mods== UFO Mod replaces helicopter model with UFO and can shoot enemy tanks Trail Mod uses Custom Launcher so game can use external Images (.TGA) files and gives game new look! (Trail was S.W.I.N.E. Experimental Prototype if you didn't know, this was even mentioned on Stormregion website.) Also use Mod Launcher.
