The Demolitionist is the raging storm that destroys masses of Zeds with each stick of dynamite, grenade, or rocket. Armed with a variety of explosive devices, Demolitionists wield an immense amount of destructive potential and can quickly turn around an entire battle with a few well-placed shots. Demolitionists can supply your squad with additional grenades while in the field and add explosive traps to any welded door, allowing them to unleash explosive hell even when they are elsewhere.

General Information

Armed with a variety of explosive devices, Demolitionists wield an immense amount of destructive potential and can quickly turn around an entire battle with a few well-placed shots. Demolitionists can supply your squad with additional grenades while in the field and add explosive traps to any welded door, allowing them to unleash explosive hell even when they are elsewhere.

Demolitionist skill choices let them focus on either taking down big lone targets like Scrakes and Fleshpounds by landing precise devastating blows or to unleash a hailstorm of explosives with improved AOE coverage and massive crowd control intensity.

Perk Notes

  • Damage modification (passive + skills): Passive damage bonus, Door Traps, Bombardier, High Impact Rounds and Armor Piercing Rounds skills affecting damage of all on-perk weapons (including Knife) or on-perk damage types. Damage ROUNDED.
  • Skill (Armor Piercing Rounds): Any hit zone that has damage scale multiplier higher than 1 is "critical". Due to their nature, explosions do damage only to the body health and does not trace hit zones so this skill will apply additional damage only through the ballistic impact.
  • Skill (Concusive Rounds): Skill increases knockdown / stun / stumble / gun hit / melee hit power for all on-perk damage types. Knockdown power multiplier of this skill stack with the Shock Trooper as a sum, total multiplier = 1 + 0.5 + 0.1 = 1.6.
  • Skill (Destroyer of Worlds): Initial explosion does x1.5 more damage than base value (and also supposed to have x1.35 wider radius, although this part does not work due to replacement of explosion-responsible actor class). For the duration of radiation cloud its damage drops down to 20 points of toxic damage. Initial explosion and radiation cloud have radius of 3 meters, cloud does damage for total of 8 seconds within 1 second intervals. Additionally ZED start suffering from the toxic DOT: duration - 5 seconds, interval - 0.3 seconds, damage scale of radiation cloud - x1.
  • Skills (Destroyer of Worlds, Mad Bomber): Players take no self damage when utilizing either of skills. Mad Bomber's explosion radius bonus (x1.25) works all the time, even outside of ZED Time.
  • Skill (Extra Rounds): C4 Explosives and Dynamite Grenades does not recieve additional ammunition.
  • Skill (Fragmentation Rounds): Explosion radius multiplier of this skill stack with the Mad Bomber as a sum, total multiplier = 1.5 + 0.25 = 1.75. This skill decreases not only explosive damage but also ballistic (impact) damage of the projectile. Damage penalty of this skill also affects blunt (melee) part of the Pulverizer.
  • Skill (High Impact Rounds): Only ballistic part of the projectile does additional damage.

Keep your eyes on the small ZEDs like Crawlers and Stalkers - as a "big ZED hunter" you are quite vulnerable to sudden close range attacks. Getting M16 for self-defense purposes is a wise choice.

Don't forget that Scrake resists to explosive damage but extremely vulnerable to ballistic impact of the RPG-7 rocket.

Boost the Dynamite's stun power by picking up Concussive Rounds. This will let you stun Scrakes and unraged Fleshpounds for a safer kills.

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

Despite the fact that Fragmentation Rounds skill actually decreases the damage done by explosives it still improves the lethal (kill) radius of the projectile if you use it against small ZEDs like Clots, Crawlers and Stalkers. On the other hand these Sirens could be a real problem without Sonic Resistant Rounds.

As a Nuke Demolitionist if you are being surrounded by ZEDs and ZED Time occurs, shoot under your feet - not it just kill and poison all nearby ZEDs but also will not harm you whatsoever. But don't try it with the Mad Bomber, it will hurt you badly.


  • According to the character's favourite weapon lines, Anton Strasser, Ana Larive and Lt. Bill Masterson and Hayato Tanaka are the Demolitionist of the team. Although Ana Larive is the only character that has 4 explosive weapons among her favourites.
  • Oddly enough the Demolitionist gains no damage bonuses towards the M16's bullets at all. For the reference the HX25's pellet impacts (which counted as "ballistic shotgun") are actually being affected by passive bonus and by Bombardier, High Impact Rounds and Armor Piercing Rounds skills.
