Hans Volter; Nazi Scientist

Hans Volter is one of the two bosses faced at the end of a standard Killing Floor 2 game. By defeating him, the game ends and the team is presented with a sizeable XP bonus as well as encouraging music and a message reading "Your squad survived". He bears the image of a disheveled old man, naked save for a pair of trousers and an exo-suit of Horzine technology that sustains his life as well as augmenting him with many powerful capabilities. He carries two StG-44 assault rifles, and wears a gas mask that seems to have melded with his flesh in some way. He appears to have a vast amount of health, which often leads to a long and potentially deadly battle. Great care should be taken when dealing with this specimen.

Statistics

- Single Player Health Reduction: 75%

Bounty £1219 £500 £425 £325
XP 1291 1694 1790 1843
Base Health (Body) 6974 7716 8162 10017
  • Hans Volter does not have head health as he cannot be decapitated.
  • Under normal circumstances, it is impossible to do anything with the bounty earned from killing Hans Volter other than to throw it around in post-victory idle time.

Notes on XP

  • XP rewarded for your on-perk weapons.
  • Killing with weapons other than your current perk grants the XP to the perk that weapons belongs to.
  • Damaging with on-perk weapons and then finishing it off with an off-perk weapon divides the XP and grants it to both perks.
  • Damaging with off-perk weapons and then finishing it off with an on-perk weapon divides the XP and grants it to both perks.
  • Assist kills grants full XP.
  • The Katana currently does not grant XP towards any perk.
  • The bash attack (default v) does not count as Berserker damage for Berserker XP, meaning it grants the XP to your current perk.

Multiplayer Scaling

- Hans Volter has his health value scaled accordingly to the number of players in the game. This increase in value is massive per player.
- Hans Volter's base health value is 7716 on Normal, 7716 on Hard, 8162 on Suicidal, and 10027 on Hell on Earth. This value is determined by the number of players that are alive when Hans Volter spawns.

Health Value (2 Player) 12204 13503 14283 17529

Health Value (6 Player) 33126 36651 38769 47580

Shield and Hunting Phase

- When Hans Volter's HP drops to certain thresholds (60%, 41% and 25%), he will put up a protective shield surrounding his body. This shield will absorb all damage done to him while it is active, and render all incapacitating effects useless, until the shield is destroyed.
- After the shield is active, Hans will toss a barrage of smoke grenades to obscure the team's vision and his position. He will then run away for a few seconds.
- After running away, Hans will charge back into team and attempt to grab a player to drain their HP.
- If Hans successfully grabs a target, he will recover a huge amount of HP over 4 seconds. This value is a percentage of his max HP, depending on what phase he is on.
- Hans will recover 32.5% HP for Phase 1, 27.5% HP for Phase 2, and 12.5% HP for Phase 3.
- Throughout the Hunting Phase, Hans' shield can be destroyed with enough firepower. The shield's HP value depends on the current phase, difficulty and the number of players.
- Note that if Hans has grabbed a player, it does not mean the team has completely failed to stop him from healing; Players can still salvage this by continuing to shoot at him as he drains his target. Hans takes around 5 seconds to complete this attack, and the shield can still be broken while he is draining the target. He may recover some health, but it is better than allowing him to complete the drain and recover a quarter of his health.
- Successfully destroying Hans' shield will end the Hunting Phase and prevent him from healing.

Speed (Sprinting) 608 - 754 608 - 754 608 - 754 608 - 754
  • In Multiplayer, Hans Volter will gain 20% bonus movement speed every minute if only one player is left alive, up to a cap of 30%. He will also gain the ability to break down unwelded doors by running into them.
  • For comparison, a healthy player character with minimal weight walks at a speed of 383, and sprints at a speed of 460.

Strategy

- Hans Volter begins every phase in "attack" mode, where he will attempt to use his weapons to shoot at players or throw grenades. He will always try to use grenades as soon as they come off cooldown.
- The team should be unloading all their weapons on Hans as he is shooting or tossing grenades, while keeping their distance and dodging grenades. Players in front of Hans should attempt to shoot his head or chest core, while players behind him should shoot his backpack core, which is a huge target.
- At 60%, 41% and 25% health thresholds, he will enter "hunt" mode, as he will chase a target in order to grab and drain their life energy. During this time, shoot at him to break his shield and end the hunting phase.
- Successfully destroying the shield will knock Hans down, leaving him open to gunfire for a few seconds and prevents him from healing.
- When a player is grabbed, immediately unload all the firepower you can on Hans. He may recover some amount of HP, but if you can destroy his shield before he finishes the draining, you can cancel the attack and prevent him from recovering the full amount of HP the attack allows him to.
- Do not crowd around him to heal his target. If there are multiple players around him, he will release nerve gas around his body when he lets go of his target.
- He will drop his target after healing to full, or if his shield is destroyed. His phase counter will increase by 1, all the cooldowns on his attacks will reset, his attack patterns and level of aggression will change.


- In Phase 1, Hans will never attempt to melee unless players get too close to him, or are standing next to him as he finishes tossing grenades.
- In Phase 2, Hans will begin tossing HE grenades, which can kill players in one hit if they are unarmored and standing directly on top of one. Make sure to dodge grenades before resuming attacking. Hans also uses his guns the least in this phase and will attempt to melee with his claws more often.
- In Phase 3, Hans will begin throwing barrages of nerve gas grenades, which can cover a big chunk of the battlefield in gas. Gun usage frequency resets to normal and he will only melee when his guns and grenades are all on cooldown, or when players get too close to him.
- In Phase 4, Hans will begin throwing barrages of HE grenades. He will attempt to spread them out as much as possible while targeting one or two players in an attempt to trap them with explosives in every direction. Take note of where his grenades land and focus on getting out of immediate danger zones before thinking about attacking him or you might be killed very quickly.
- In Phase 4, Hans will throw grenades very frequently and use his guns less often, instead preferring to melee with his claws. This phase is extremely dangerous as losing track of his grenades or being targeted by his melee can lead to swift deaths. Keep your distance as much as possible.


- It is highly recommended for each team member to purchase the HMTech-101 Pistol before this fight begins, as it will allow for the team to heal each other throughout the battle. Seeing as Hans puts out quite a substantial amount of damage, and the HMTech-101 Pistol is relatively inexpensive, this action can vastly help your team to survive.
- In the absence of a Berserker, it is also recommended that some team members carry a melee weapon (such as a Zweihander, Pulverizer or Katana to parry Hans' melee attacks. Hans' melee attacks are the most powerful in the game and he can easily rip apart unarmored players in 2 hits, and being able to defend yourself when Hans charges at you is important.
- Successfully parrying some of his attacks can stumble him and cancel his melee, which may prompt him to use his guns or toss grenades instead.
