On the endor like map that is not the swamp map, if you jet into the corner of the power generation room, you will
go down to a second level under the map, where you can't move but don't die.
It's a good place to hang out and wait for the map to end if you are empire :P
Another glitch with Heroes vs Villains. At he start of each round you play as a soldier rather than a hero you cannot use your Star Cards, you cannot restart either so you have to kill yourself to make your Star Cards work again.
I think i found a glitch in the Battle of Jakku, Turning point. During the second round of base captures, after you have captured the first 3, go to the base on the left that looks like it is in a big parking lot. There is a crashed TIE fighter NE of the dotted circle of the base. If you kneel down next to the outside wing, get as close as you can and you will get stuck. That sucks but the enemy can not see you anymore and the enemy spawns right in front of you during the third round of base captures. You can shoot them at your leisure. They will run right by you and no one can see you. Be careful though b/c they can see the shots coming from the TIE and still shoot you. Make sure you have a grenade b/c if no one shoots you, you will be stuck for the entire game.
