If you have Burnin' Rubber 3 Standalone and gained the World Domination trophy you can unlock the tank by putting your BR3 savegame in the BR4 save folder. You can find your BR3 save game at C:\Users[YOURUSERNAME]\AppData\LocalLow\Adobe\Director 11\BurninRubber3\Prefs\XBR3Data.txt Copy and paste it to C:\Users[YOURUSERNAME]\AppData\LocalLow\Adobe\Director 11\BurninRubber4\Prefs Unfortunately we cannot automate this process. Start the game and claim your tank!
