Boltcaster
The Boltcaster is an energy projectile weapon that uses Projectile Ammunition. The source compares its role to a pistol and names Barrel Ioniser as an upgrade.
How it works
The technology entry places the Boltcaster among multitool offensive weapons, identifies it as an energy projectile weapon, and states that it needs Projectile Ammunition. It also names Barrel Ioniser as a Boltcaster upgrade but gives no upgrade effect.
When it helps
If you want the source-described projectile weapon and can supply its ammunition, consider the Boltcaster. The evidence does not establish comparative damage or whether it suits a particular enemy.
The tradeoff
It requires Projectile Ammunition, and the listed upgrade has no described effect in this source.
Your next step
Check ammunition availability and the current Barrel Ioniser description before installing related technology.
