The Link Gun is a weapon that fires green plasma bolts in rapid succession. Although the bolts themselves travel slowly compared to most of the other guns, this weapon has a fast rate of fire.
The weapon appears in Unreal Tournament 2003 and 2004 replacing the Pulse Gun, and the secondary beam can be used to "link" with another player also using a link gun, that player gaining a damage bonus. Secondary fire also repairs nodes and vehicles as well as reducing an opponent to a skeleton, if the beam deals the final blow. Primary fire shoots plasma bolts like the Pulse Gun. It reappears in UT3 and again in UT4, with the same role.
