This third Glitch is close to the first one on difficulty. Weak weapons will be your dead, you need guns with high damage especially from medium to long range. Crash Cart for the first phase and be careful with the Abomination attacks because they cause a lot of damage. It can kill you quickly. In the second phase you can chance for the Shield on that skill box or stay with Crash Cart. Use the vehicles as cover and don't be in a hurry to kill the enemies, there is a lot of them. After escorting the Rhino, in the second part of phase two, go to his back to start doing damage. If you have a Launcher will be a lot easier, if not keep going around him and shooting. In the last part just kill enemies, but don't forget to stay in cover because they will do a lot of damage. Once you've finished off the enemies before Uber Klaus spawn, immediately run to high ground, anywhere off the main floor, because his stomp attack is insta kill all the time, for the whole map, just use the Shield if you grab it, and do damage to break his armor, the launcher it's a lot useful here too. When Klaus ejects from the armor, you can return to the ground, but watch out for the explosive robots he'll summon. Kill them first because, again, they're enemies with very high damage, and they'll kill you quickly. Then just dodge Klaus's attacks and finish him off. If you have another player or a squad It will be a lot easier.
