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.
Apparently, simply remaining active will allow you to continuously participate in online matches for Battlefront II. Just for participating, you get credits. Of course, you get credits for accomplishing tasks and being a general team player, but simply being "active" gets you a small amount of credits. Some people have rigged up a few "hacks", if you will, to fool the game into thinking there's an actual human participant behind the controls. Using methods such as the ones depicted, allow a player to read the classics, learn a new language, or even find the cure for cancer, instead of actually playing the game. All the while, earning those credits so you can buy neat stuff in the game. It certainly doesn't do much for your teammates to have one of their members spinning in circles throughout the entire match, but who cares about teammates?
