Weapon Special: Cycle between semi-auto, three burst shot, or full-automatic modes (also can be changed to allow dual-wielding Carbines; LMG replaces any of these with toggleable laser sight in version 2.03). In version 3.0, if the weapon is upgraded to Light Machine Gun, then instead you can switch from "drum magazine", which has 60+1 max ammo in the drum, or "ammo belt", which disables reloading, but also disables usage of ironsights, and decreases accuracy. In 3.0 the weapon special brings up a wheel, which allows the switching between any of the aforementioned fire modes, as well as dual wielding. As of 2022, the LMG now also has a Micro-Missile special, which replaces the ammo belt mode in the original. The micro-missiles spend three bullets per shot but each shot is very deadly and can kill a group of lesser tier enemies in seconds.
Hey. I wanted to point out that I found some of the new weapons legit. According to the wiki they spawn in later levels. Used a cheat code to teleport to one of the later levels. Got a heavy machine gun and hell rifle right away as drops from enemies. I also found the revolver on MAP11 sitting there.
Those who use the GiveItem cheat will receive any item that they specify on the command line, meaning you can arm yourself with weapons or give yourself specific building pieces as needed. 2b1af7f3a8
