During each "special event" you unlock XP each time you beat a wave. If you get 19,250 XP (I think that was the amount for gats) you get to unlock the gatling truck in the event store. If you get another 19,250 XP, you can go and unlock elite gatling trucks. Note, any tech center leveling you do to the gatling truck will transfer to the elite gatling truck (the elite version basically replaces the normal version in your inventories).
