Up to three Boltcaster Upgrades can be installed in the inventory of the Multi-tool. Installing four or more upgrades will disable all upgrades of that type until the upgrade count is reduced to three or less.
Crafting[ | ]
Boltcaster Upgrades can only be obtained by installing Boltcaster Modules.
Upgrade modules follow a static progression. The generation seed is used for all module families at the same time. During module installations it goes up by one. The new module they change into correlates to their order of installation. If the game is reloaded, the exact same pool will be offered to the player, no matter the order they install other modules.
Example: If an S-class module had 200 ly Hyperdrive Range bonus on the third installation no matter in what order the former modules are installed or their class, if the same S-class module is used third again, it will once again be the 200 ly bonus module even if the name changes. Only if used second or fourth the module stat may change.
Discovered Upgrade Modules[ | ]
ID value can be established by using NMSSaveEditor, and this is the "seed" that determines what bonuses this upgrade will provide.
Boltcaster shots affected by the Ricochet Module bonus are unable to damage reinforced doors, supply depots or Sentinel Walker torsos on direct hits. (It is not yet known whether shots are able to damage armored targets after a bounce.)
