―Official Description

The Zerfallen is a [PREM] Version Energy rocket launcher that was released on April 28, 2016. It was initially found in the "Easter Patch", although without any stats. On April 22, a user hacked into the game's files and was able to leak the stats of the presumably upcoming gun. The user posted the weapon stats on the forums, although the post was taken down approximately 11 minutes later.

The gun seems to be very strong for its classification. However, this comes at the price of having only 2 shots in the clip, alongside with a huge 80% movement penalty. The Zerfallen appears to launch a 6 Meter diameter blast of energy that looks like a bloated version of the impact of the Torment but it's blue instead of red. The blast radius also appears to be very huge. It also has the ability to paralyze/pin zombies in place (Also making them unable to do normal melee attacks) that survived the shot, however, this doesn't work on some bosses like Loaderbots, Zombie Mech, and Necrosis Spawns. Adding a base core is extremely recommended for an extra ammo. There's a bug on this weapon where if you fire the weapon and there's a puke worm present in melee range, the orb just instantly explodes. The orb is capable of damaging an enemy twice if they are near a wall, once from getting hit by the orb and the explosion damage when the orb hits the wall. It costs 400 NK coins or $39.99 USD, making it one of the most expensive [PREM] Version weapon in the game, along with the Torment, HIKS 888 CAW, and the CM 000 Kelvin. Zerfallen appears in the store along with Torment and CM Proton Arc

Build info[]

The zerfallen is the best bossing weapon in SAS4 mobile and is decent in many other areas. Its good for faction eggs, Uranium Mine contracts, bossing in events, and even mobbing if used correctly. Has many massive weaknesses, namely extremely long reloads, so you'll need a specialized build and some practice to use it effectively. The best augments for zerfallen are deadly/adaptive/skeletonized/overclocked(4th) for bossing (nightmare and events) and skeletonized/overclocked/enlarged or race modded if reload isnt capped for xp grinding in contracts. It averages 1150-1200 kills in singleplayer contracts if used properly. Zerfallen is best used on pc as mobile controls make it more difficult to use. As for the web version, its seeing use there as a decent mobbing choice for apocalypse mode, however, there are usually better choices available.

Trivia[]

  • Initially, this weapon had 50,000 damage, which was changed to 55,000 on April 26, 2016, and then nerfed to the 35,000 damage we have today.
  • As the description says, it deals half damage to bosses. However, the blast can deal full damage to any boss.
  • In the description, it says that the Zerfallen uses JOLT Technology. This is probably referring to the Jolt Ship that destroyed Thera on the mission Vaccine, suggesting that the Zerfallen uses similar technology.
  • The orb the Zerfallen fires can travel through the subway's doors on Vaccine, and possibly the doors where the Vaccine itself is located although this has not been tested.
  • It is the second heaviest weapon in the game, the heaviest is HIKS M1000 (Championship gun)
  • "Zerfallen" means "Decay" in German
