The BDL-23 Dohvat Laser Designator is a regular laser designator, the Dohvat will paint an area with a laser. The painted area comes under heavy fire within seconds. The battery has enough power for 16 designations before reloading.

The Exoskeleton is a bipedal weapon platform which represents the latest in the ISA's development of war machines for their war against the Helghast.

The Pnv-3 Siska Squad Cannon is a huge behemoth and a super-large equivalent of the recoil-less rifle. In fact, asking if the Siska is recoil-less would make any Helghast laugh. It fires anti-tank rounds with so much force that you don't feel the recoil because a servo-operated gyro-mount is required to keep you from becoming a literal human cannonball. It has six rounds. Like the LS13 Shotgun, it can fire one or two rounds at time. However, the two round shots arc in a manner similar to that of the BLR-06 Hadra MRL, but they have less of an arc and a bigger spread pattern.

The VC1 Flamethrower is a flamethrower manufactured by Visari Corporation. It was a weapon in Killzone: Liberation, and is first found in Killzone 2 during the mission "Salamun District". Later in the game, it is used by Helghast army Pyrotroopers.
It projects an ignited stream of flammable liquid at high pressure, allowing the user to arc the stream behind cover and splash nearby enemies; the flammable liquid itself consists of low-octane gasoline and an unidentified component indigenous to Helghan.

The VC5 Arc Rifle is one of the latest additions to the Helghast arsenal and is manufactured by Visari Corporation. The VC5 holds four reservoirs of weapons-grade petrusite, a solution which draws energy from the surrounding air and condenses it into one or two high voltage charges. When fired, the electrical charge locks onto the closest conductive target and other targets close enough to that target. It has interuptable reload, which is ideal in the middle of a fight.

The VC21 Boltgun, also known as "the Handyman", was originally built as an industrial tool before being modified into a weapon by the early Helghan settlers and is manufactured by Visari Corporation.
The high-speed bolts the Boltgun fires are able to pierce standard Helghast armor, sending most enemies flying backwards and pinning them to the nearest surface before finally exploding a few seconds after impact. It is only found in the Suljeva Village and Tharsis Refinery missions, usually on Miners or in weapon racks.
