Part 3: Super Soldier
Map Name: boss2
Before the cutscene, there are five enemies to kill. The first is a Proto Soldat with a Venom Minigun. Next there are two Soldiers with MP40s; one is at the top of each of the stair cases. After these Soldiers, there is another Proto Soldat (this time with a Panzerfaust) accompanied by a Flame Trooper.
Wait until after you have killed these enemies before collecting the health and armor at the beging of the level; this will ensure that you have full health and armor before the big battle. After the cutscene, you will not be able to go back for these items so get them now and switch to the Panzerfaust.
When the cutscene is over, move forward and fire one rocket at the Uber Soldat. Quickly jump down and run to your right where there is a closed off area that offers you some cover. When in here, the Scientists on the scaffolding above will have a hard time hitting you. If you can kill them without exposing yourself to the Uber Soldat, you should; however, they do relatively little damage compared to the Uber Soldat so don't take any risks trying to kill them.
By running from one side of the closed off area to the other, you can keep the slow Uber Soldat from getting a good shot at you (he basically walks to whichever end you are at). Come out from the area briefly to shoot him with the Panzerfaust (or Venom Minigun when out of rockets). He and the other enemies will be able to damage you when you expose yourself to do this, but there is no way to get around this.
This Uber Soldat is armed with a Panzerfaust and a Tesla Gun. Both do a lot of damage. While it is possible to dodge the rockets, you can not avoid the Tesla Gun when in the same area as him. Thus, it is important to remain in the sheltered area as much as possible.
Eventually, you will kill the Uber Soldat. There are armor and health pick-ups along the walls near where the Uber Soldat emerges. You should not go for these unless you are very low on health. When you go for them, it is very easy for the enemies to damage you.
After the Uber Soldat is dead, you will have to finish killing the Scientists that stand between you and the exit. This should be very simple since you will have his Tesla Gun.
