Bonus Experience

Supports receive bonus XP for welding doors. Additional XP reward given for building up every 510 points for welding meter.

Hell on Earth
Bonus Experience

Each Support has its own "welding" meter. When welding the door (un-welding does not count) with each Welder's attack this meter increases by Welder's weld rate (from +68 points at level 0 up to +102 points at level 25). When meter filled, i.e. has 510 points on it, it resets and player recieve additional XP reward. The meter does not become zero but instead begin with a leftover from the previous welding cycle. For example the player who had 500 points on the welding meter and then added +102 more points by single Welder's attack will get XP and initiate a new cycle with 102-(510-500) = 92 points on the welding meter. Support can build up its welding meter from multiple doors, the meter assigned to perk not to the certain door.

Perk Notes

  • Damage modification (passive + skills): Passive damage bonus and Salvo skill affecting on-perk weapons or damage types (including Knife, excluding Frag Grenade explosion) and shard damage. Damage ROUNDED UP.
  • Shotgun penetration modification (passive + skills): Passive bonus adds up to +5 points on top of the base penetration power of the weapon. Armor Piercing Shot skill adds 4 more points. For the duration of ZED Time Penetrator skill replaces effect of Armor Piercing Shot and adds 40 more penetration power points to the weapon's base penetration power (for up to +45 points at level 25). Additionally for the duration of ZED Time, when Penetrator skill active, weapons will not suffer from the damage reduction on each subsequent penetration.
  • Passive (Ammo Backup): Amount of given magazines per interaction is a maximum out of two possible integer values - (Initial Spare Magazines / 1.5) OR 1, for secondary ammo to give - (Ammo Pickup Scale x Magazine Size) OR 1. Additionally Resupply Pack skill multiplies these values by x1.3. Resupply Pack skill DOES NOT increase amount of the ammo given to teammates.
  • Skill (Concussion Rounds): Skill works only with on-perk weapons.
  • Skill (High Capacity Mags): Skill excudes Double-barrel Boomstick and Doomstick.
  • Skill (Resupply Pack): Skill multiplies amount of ammo given to teammates by x1.3 (see Ammo Backup). Total amount of ammo given is an integer value of INT(Initial Spare Mags / 1.5) x Mag Size x 1.3, for secondary ammo (e.g. M203 grenades) - Ammo Pickup Scale x Magazine Size x 1.3. Skill allows to replenish ammo and armor separately. Skill icons: red - player can resupply both - armor and ammo, yellow - player can resupply either ammo OR armor (depending on what has been taken earlier), grey - skill inactive. Skill resets at the end of each wave.
  • Damage type: Damage type "Ballistic_Shotgun" includes all the damage types used by Support's on-perk shotguns.

On-perk Weapons

Following weapons and damage types are associated with the Support. They are getting damage bonuses and buffs to their attributes from the respective skills:

















Great perk to control ZED crowd at the choke-points.

Quite effective against Gorefasts and Gorefiends thanks to their native weaknesses to shotgun damage.

Use the extra carrying capacity ability to arm yourself with the HMTech-301 Shotgun or lightweight HMTech-101 Pistol.

If you planning to take down Scrake solo, the Double-barrel Boomstick's headshot is a good starter. It has a lot of stumble power which would give you enough time to reload the weapon or to switch to more powerful shotgun.

Work together - combine the passive ability to restore the doors with Demolitionist's Door Traps ability to set up explosive traps. For better effect don't forget to keep the door "alive" until it would have enough ZEDs behind it.

Utilize Double-barrel Boomstick's special knockback feature to get off of the ZED's melee attacks and to mitigate the falling damage too.


  • According to the character's favourite weapon lines, Donovan Neal, PC Rob Briar, Classic Briar and Mr. Foster are the Supports of the team. Although only Donovan Neal and Mr. Foster are the only characters who prefer AA-12. Many other characters are enjoying the M4 shotgun and Double-barrel Boomstick as well.
