About this mod Author’s original text

GP-31 Grenade Pistol (from Helldivers 2)

The tactical utility of a sidearm capable of firing 40mm grenades is not to be underestimated; potential uses include taking care of clustered light infantry, dealing a powerful blow to a larger enemy, and shattering both cover and tactical objectives. This was the thought process behind the sleek GP-31 Grenade Pistol, a staple of SEAF tactical equipment and favorite among the Helldiver corps. Loading and operating not unlike the older M203 grenade launcher, the breach-loading GP-31 is concealable and powerful, enabling its operator to place 41mm grenades where and when they are needed. Just don't miss your single shot, because reloads aren't exactly instant.

Features

  • GP-31 Grenade Pistol (High-explosives in a sidearm slot? Sign me up! Found under grenade launchers in the item spawner)
  • 41x45mm SEAF grenade (A potent yet slightly slow grenade with lots of filler)

Install & use Install: BepInEx plugin

  1. The archive from playbuff is the mod itself — usually a BepInEx plugin (a .dll or a plugin folder once unzipped).
  2. Recommended: use a community mod manager (such as r2modman) — pick this game, import the mod, and the manager sets up BepInEx and its dependencies for you.
  3. Manual route: install the BepInEx loader in the game folder, then drop the unzipped .dll or plugin folder into BepInEx/plugins/.
  4. Launch the game — the BepInEx console logs every plugin it loads; seeing this mod in the log means it is installed.

Mods with listed dependencies need those installed too, or they will not load. Options are usually changed in-game or in the plugin's config file.

Dependencies

Install these first, or the mod will not work:
