343 Industries has unveiled a new EMP-resistant mech for Grunts, the Grunt Goblin, and the UNSC's new Wasp light aircraft, both of which are set to arrive in the world of Halo 5: Guardians in the free upcoming Warzone Firefight update.

The menacing Grunt Goblin, exclusive to Warzone and Warzone Firefight, is best dealt with from afar. Players may be tempted to get in close to destroy parts of this Grunt-controlled battle suit, but that's a terrible idea, 343 Industries character designer Steve Dyck revealed in an interview with Polygon.

For soldiers who get too close, the Grunt Goblin can dispatch them in a single blow. And for drivers bold enough to get in close, the Grunt-controlled suit can disable vehicles with an EMP blast.

Don't think about trying to hijack a the Grunt Goblin, a battle suit Proctor said was made "by Grunts for Grunts."

"Unlike other vehicles, the Grunt Goblin cannot be hijacked or boarded and has a complete immunity to EMP effects," said Proctor. "Don't waste your time (and REQs) on plasma pistols!"

The Grunt Goblin can take the field in Mythic or Legendy form. They can make quick work of Spartans and Spartan vehicles alike, thanks to a double-barreled heavy needler and a needler barrage that can strike up to eight targets at once.

Players can take out the Grunt Goblin's backpack to disable the needler barrage and expose a soft point on the battle suit's back, where hits produce bonus damage.

On the opposite side of the battle lines and an inverse of the Grunt Goblin's fighting style, there's the UNSC Wasp. While the mech is a menace up close and can take a pounding, the Wasp, and its light armor, are meant for quick strikes and evasion — but that it has the munitions to make those quick strikes count.

"In fiction, the AV-49 Wasp supplements existing stocks of AV-14 Hornet and AV-22 Sparrowhawk aircraft in UNSC Marine service," said Tim Temmerman, systems designer. "It is a close air support VTOL armed with heavy machine guns and twin rocket launchers."

The Wasp and the Grunt Goblin were the only two pieces of new content 343 Industries was ready to talk about with regards to the Warzone Fighterfight update. For more details on the Wasp and Grunt Goblin, head over to Polygon.
