New weapons

Two new weapons arrive with the mid-season update – the Sledgehammer Melee weapon and Reclaimer 18 Shotgun, which fans will remember as the SPAS-12 from MW2 (2009).

The Reclaimer 18 will be available through the Classified Sector in the Season 4 Battle Pass. Meanwhile, the Sledgehammer will be available as a Weekly Challenge reward.

New maps & variants

On top of the new weapons, Season 4 Reloaded also introduces a brand-new map along with several variants. The new 6v6 map Incline is “a mid-sized snow map” set in the mountains of Urzikstan, perfect for mid-range Assault Rifles or SMGs if you venture into the main transport facility.

Das Gross, a reskin of the popular Das Haus that coats the map in “revolting preternatural tendrils and flapping tentacles,” is another Vortex variant that will be added to the playlist’s pool, which also returns with the mid-season update.

Additionally, a new playlist called Bit Party arrives, featuring a “pixel-art inspired version of Favela” where killing enemy players inflates your Operator’s head making you an easier target to hit.

The parkour Get High mode returns with the G3T_H1GH3R version featuring a new “retro-futuristic utopian voidscape,” with a ton of “newly repositioned floating geometric neon-grids and platforms.”

New modes

Season 4 Reloaded brings several new modes into the game, including Mutation, and classics such as Headshots Only or Blueprint Gunfight.

Mutation is part of the Altered Strain event pitting “one team of humans against a frightening selection of mutants.” Humans will be regular Operators with the standard loadouts and an increased ammunition reserve.

Mutants will possess a “series of unique abilities that can stun, disorient, and eliminate enemy humans.” Additionally, they’ll have help in the form of “non-player controlled Mutants.”
