There are two ways to unlock the stuff in Star Wars Battlefront II. You could pay directly or you could build a robot to keep up in your place. Of course, you could also play but the time to unlock a hero is quite high.
Lowberg opted for the drastic solution, building a nice robot that obviously can not play properly, but can do enough to keep him from knocking out, jumping and moving the player around the map, collecting the minimum points for participation in the game.
A somewhat special idea that may even be emulated by other people.
