How to Unlock the M175 "GRIM" in StarRupture; Attachments, Upgrades and More

The StarRupture M175 Grim is a strong machine gun in the game. It’s a fast-firing weapon that becomes more effective as you start upgrading it with attachments. To unlock and upgrade it, you will need the War Bonds in both cases. In this guide, we will explain how to unlock StarRupture M175 Grim and collect the War Bonds.

How to Unlock the M175 “GRIM”

The StarRupture M175 GRIM Infantry Machine Gun is a powerful, high-fire-rate weapon for fighting with enemies at mid to long range. You can unlock the base weapon for 110 War Bonds at the Equipment Upgrade Station. Once you have it, you can customise it. You can spend extra War Bonds to unlock add-ons like different magazines, stocks, and other attachments. You can build a loadout that fits your playstyle.

To use the Equipment Upgrade Station, you will first need to unlock it. This happens once you reach Level 4 with the Griffits Blue Corporation, which requires a total of 6,400 corporation points. Just keep completing activities and earning points for the corporation, and you will gain access to the station as you progress.
