The Midge-Mong boss battle in Borderlands 2 is the first optional boss battle of the game. It is billed as a level 5 mission, but the mission is actually quite a bit more difficult than that. If you are going to tackle this mission, you should try to acquire some rather quality equipment first or gain a few more levels. Follow the instructions in the Midge-Mong boss battle guide below to deal with this optional boss.
Suggested Level: 7-8
A good bit of the difficulty with this boss is that you have to fight through some higher level bullymongs just to even get to the town where the battle occurs. Then you have to fight through the town itself, though this is a mixed blessing, because while some of the enemies are tough, the town has a lot of lootable items. The battle itself is a bit random. If Midge-Mong plays nice, you can beat it easily at level 5 or 6. But most of the time you will need the higher gear available at higher levels.
Midge-Mong might get up in your face or might go to the opposite side of the map and there is no way to predict this. A good sniper rifle and a solid close range weapon covers both possibilities. If you are weak in one category, don’t worry. You have a chance to upgrade weapons after the battle starts. There is a weapon shop, ammo shop, health shop, and treasure chest in the room that Midge-Mong appears from.
You need to climb all the way to the top of the highest building in the town where Midge-Mong appears and then open the double doors. The boss will charge out of the room he starts in and jump down to the level just below. The entire fight takes place throughout the town, though Midge-Mong prefers to fight in that area where he first jumped to and a balcony at the back end of the town. He will only go to lower levels if you go there first.
When the boss first appears, ignore him and loot the room he comes out of. Between the chest and the shop, you should be able to fully upgrade your weapons as well as max out your ammo and health. This shop is a safe location. Any time you need a breather you can run back in here and no one will attack you. This is particularly important because sometimes this boss will break out of his normal AI and charge you relentlessly. Assuming you survive that, you will need a place to recover.
Leave the room and look down. Midge-Mong will be running around on a plateau just below him. If you want you can start shooting him now. If you do, he’ll fight back a little and then flee to the balcony on the far side of town. If you actually go toe to toe with him, he won’t flee, but that bullymong he is riding deals massive melee damage, so be careful.
Gaige gets off easy in this fight. Deathtrap will distract him and you can shoot him freely while those two fight. Deathtrap will die before he does and then he will retreat to the balcony. Axton has it almost as easy since you can place the turret in a location that can shoot Midge-Mong where he is now and the far balcony.
The other characters have it tougher. For now, simply shoot him with the highest DPS weapon you have. He’ll lose about a third of his health before fleeing and even if he hits back, you can heal up at the shop real quick. When he flees to the balcony, pull out a sniper rifle and hit him with head shots. He will shoot back, but at that range he won’t hit much. When his health gets low, he will get more aggressive. This is when you pull out your action abilities. Try to lure him back to where you initially fought him. It is an open area and he likes to go there. Go on full offense using your action skills liberally. Only Zero might have any real difficulty and only if he gets unlucky on his sneak attack.
You actually will have gotten most of the rewards for this boss battle before ever fighting Midge-Mong. In fact, if you want to, you can loot about two to three chests in town without actually fighting the boss. He will drop loot, but since he is a lower level boss, it isn’t anything spectacular.
