To complete this mission you have to beat the big enemy at the way at the top.The big one will be covered with sandbox soo you need to break some of it and kill the big one.The big one might not do anythinmg if your lucky because he may not have no space to attack.Good luck,enjoy,rate,comment,vote if you like it.Note this isn't part 3 of the Counter Escape this is the boss part.
(NOTE:The sky is limited due to putting decoration around the map soo i put blocks around the area to stick with killing enemy's.)
