The economy of Star Wars Battlefront 2 is based entirely around credits now that premium transactions have been removed from the game, and earning enough credits to buy the loot boxes to get the cards you need or to unlock the heroes you want can take a lot of time. So clever players have found physical ways to cheat the system.

While one player created a simple robot to keep their character moving in order to farm credits without being removed from the game due to inactivity, the same thing can be done by simply adding a few rubber bands to your controller.
