For Alpha Squad purchasers, how can I equip the 10% xp boost (where do I even find it)? or is already applied without taking up the boost slot?
You need to equip the boost implant. I did that from the main character screen, the icon at the extreme left of the bottom of the map screen.
press m then your stats icon far left then top righ corner it should say 10% xp gain , drag it into the empty slot on the left , if i remember correctly
