Alongside the new Moonbase map, Interstellar Insanity includes four new weapons and a number of cosmetics for Zed hunters to get their grubby mitts on. The Blast Brawler gauntlets will help Support smash Zed heads and push enemies back to keep allies alive, while the HRG Bastion LMG gives SWAT an extra buffer against the horde with an energy shield. 

The summer update also includes two paid DLC weapons in the FAMAS Masterkey for Commando and Support, and the Thermite Bore for Firebug. The FAMAS features an underbarrel shotgun and ACOG scope, and the Thermiote Bore features sticky grenades. 

The two new weekly modes are Arachnophobia and Scavenger. Arachnophobia ups the spawn rate of crawlers and increases their health pool, while Scavenger removes all weapons from vendors, forcing players to pick up on the map. 

Developer Tripwire Interactive also said in a Steam update that a number of bug fixes have been issued with this update, and that they have also implemented some user feedback in the form of “quality of life” changes, tweaking some perks and rebalancing certain weapons.
