12.7x55mm Ammo

A massive Russian cartridge designed for extreme stopping power and generally being big and stupid, 12.7x55mm comes in two different variants for different weapons platforms. The shorter PS-12-type bullets are for use in the ShAK-12 rifle and RSh-12 revolver, while the longer STs-130-type are for the VSSK Vykhlop sniper and its derivatives.

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:
