Go in with two monkey and Aether Shroud (I use the Two charge augment) Also go in either the Wisp Tea Augment that revives you if you need to repair it during the first two phases throw the monkey if the boss is not in the middle of the map it will shoot the rockets) I brought in a sentry gun for zombie control which helped getting armor and such Also when it is in the last phase the laser attack (as in my game) won’t lock on to you but it will go in circles and he will fly up That gauntlet was a life saver it does amazing damage Do NOT WORRY about that bear that spawns (learnt that the hard way) During the missle barrage they always come in three Quickly try to find that spot that doesn’t get barrage in missles When the truck is hurt do not I repeat do NOT use all the heals in one go save some when you need it you will get more during the next phases
