This trick is most useful when using equipment such as the Recon Droid and sniping for Battlefront 1 (There are infinite ammo and health codes on Battlefront 2 but it's basically the same thing ). To do this just simply stand by a Ammunition Droid and it will replenish your ammo at all times unless it gets destroyed. This also works for health and Health Droids but most of the time the AIs will throw a grenade. Enjoy your infinite tubolaser strikes and health.
