Black Sun - Wolfenstein
Grab the ammo on the table along the walkway and approach the portal at the other end to face Hans Grosse.
Objective: Defeat Hans Grosse (Phase 1)
Hans Grosse is on the platform in the middle of the arena. A shield surrounds the platform, so you must use Empower to plug through it. The Leichenfaust 44 is the weapon to use here; it’s even better if fully upgraded. Dodge the line of bullets at the start, equip the Leichenfaust 44 if you haven’t already, activate Empower, and blast Hans Grosse through the shield.
If you’re playing on the normal difficulty level and have a fully-upgraded Leichenfaust 44, Hans Grosse should falter for the first time after only one hit. After he falls to one knee, he’ll destroy one of the pillars circling the platform. There’s a Veil Energy source on each pillar; immediately after downing Hans Grosse, deactivate Empower, activate Shield, and sprint toward one of the approaching pillars.
Use Empower to hit Hans Grosse through the shield surrounding the platform.
The pillars are fast, so don’t try chasing after one; sprint to an approaching one and hug it to be pushed around the arena. You’ll restore some Veil Energy (a half or three-fourths of your meter depending on the upgrades you’ve purchased) while hugging one of the pillars. When the Veil Energy source disappears, activate Shield and Empower. Then, fire at Hans Grosse while sprinting toward another approaching pillar. You should be able to hit Hans Grosse once or twice before your Veil Energy is completely depleted.
When you reach another pillar, allow it to push you around the arena. If you downed Hans Grosse and he destroys the pillar you’re hiding behind, activate Shield and Empower and sprint towards another approaching pillar. Even if the pillar you hide behind is destroyed soon after you reach it, your Veil Energy should have been restored enough to allow you to seek out another without taking too much damage.
Repeat the above strategy until Hans Grosse falls. At that point, approach him, press the Y/Triangle button to grab him, and then RT/R2 to have B.J. stab him with the Shield crystal.
Completing first phase of the Hans Grosse battle.
Objective: Defeat Hans Grosse (Phase 2)
You’ve lost the Shield power, so you must be especially careful here. During this phase, Hans Grosse will race around the arena and fire his machine guns at you. When he’s damaged significantly, he’ll retreat to the sky and shower the area with missiles. There are plenty of obstacles to hide behind but Hans Grosse’s speed can be a problem. The Mire power can fix that, though.
At the start of the round, head straight and turn left when you reach the wall. Continue heading south until you encounter Hans Grosse. If you reach him fast enough he should be inactive; don’t shoot him yet, as you’re shots won’t register until he starts moving. When he speeds off, head a bit further south until you come to spinning cog on a pillar with a Veil Pool beneath it. Wait around here until Hans Grosse appears, at which point activate Mire and fire at him with the Leichenfaust 44 (or, if you’re out of ammo, another weapon such as the Particle Cannon) until he falters and retreats to the sky. Deactivate Mire as soon as you see him falter to conserve energy.
Use Mire to slow Hans Grosse down.
While in the sky, Hans Grosse will fire missiles at you. Stand in the Veil Pool under the spinning cog on the pillar to restore some of your Veil Energy, and also shield yourself from the falling missiles. The Veil Pool will soon disappear, but will eventually reappear, allowing you to restore even more energy. Remain below the cog until Hans Grosse lands. Even while Hans Grosse is on the ground, remain around the cog so you can return to it as soon as he takes to the sky. When you encounter Hans Grosse, activate Mire and fire at him until he falters, or until you run out of Veil Energy.
Repeat the above strategy until Hans Grosse falls. Then, approach him, press the Y/Triangle button, and then RT/R2 to have B.J. stab him with the Mire crystal.
Completing second phase of the Hans Grosse battle.
Objective: Defeat Hans Grosse (Phase 3)
When you hit the ground, collect the ammo on the tables below the tent (particularly the Leichenfaust 44 ammo) and start toward the walkway to the east. Hans Grosse is sitting on the side of the mountain further up; he’ll continuously fire missiles along the path, so you’ll have to sprint through. It’s nearly impossible to get through this without taking damage, but dodge the missiles to avoid taking a direct hit, which would surely result in death.
Once you’re past Hans Grosse, stand on the magic lift at the end of the path to ascend to the next level. Here, look up to spot a mass of red crystals. Fire at the red crystals with your Leichenfaust 44 to destroy the rock bridge. Make your way to the end of the path to uncover a Veil Ladder.
Completing third phase of Hans Grosse battle.
Objective: Defeat Hans Grosse (Phase 4)
Before climbing up the Veil Ladder, equip the Tesla Gun. There are Sniffers at the top of the ladder, so sprint away from them as soon as you’re at the top of the ladder and use the Tesla Gun to zap them. When the first batch of Sniffers has been taken care of, start down the path. More Sniffers will appear, so zap them with the Tesla Gun and continue following the path. At one point the Sniffers seem to spawn indefinitely, so you’ll have to sprint through while holding down RT/R2 to reach the pillar Grosse is standing on.
When you reach the pillar, Grosse will hop off and run to the end of the path. There, he will continuously fire at you as you approach. Sprint and dodge to the side to avoid taking damage, and then hit Grosse with gunfire to push him off of the ledge. You should automatically begin to ascend to the final battleground.
Hit Hans Grosse with gunfire to push him off of the edge.
With Empower and a fully-upgraded Particle Cannon you can end this fight quite quickly. Sprint to the machine in the middle of the arena and take cover behind some rubble as Hans Grosse descends. Equip your Particle Cannon (which you should have plenty of ammo for) and wait until Hans Grosse steps off of the lift.
With Hans Grosse in your sights, activate Empower and move around while firing at him with your Particle Cannon. While hitting him with the beam, dodge to the side to avoid taking fire. Grosse is weak at this point, so even if you don’t have enough Particle Cannon ammo, any other big weapon with Empower would do.
Continue attacking Grosse until he falls. Then, approach him, press the Y/Triangle button, and then RT/R2 to have B.J. stab him with the last crystal. That last stab will do him in.
Defeating Hans Grosse.
