Plasma gun/Doom 3

"Energy based weapon developed in the Mars weapon facility. Unit is powered by plasma canisters manufactured in the EnPro facility."

- PDA Description

The Plasma Gun in Doom 3 is an energy-based weapon first found in a hidden location in Sector 3 of the Alpha Labs. It is slightly different from its earlier counterpart, as the weapon model is based off of a futuristic modern assault rifle with a bullpup design (the weapon ammo is reloaded and ejected on the back of the weapon). The weapon fires blue plasma bursts which originates from the cells stored inside the back of the weapon. Similar to the Chaingun, BFG 9000 and newcomer Machine Gun, the Plasma Gun discards the game ammo HUD because it has its own ammunition counter in a small monitor located at the rear upper end of the weapon itself. Ammunition comes in the form of Plasma Cells, which appear to be bulky bottles that glow a luminescent blue and possess a blue-colored tip. Individual Plasma Cells hold 25 units of projectile, whereas a box of 2 Cells holds double the amount. Ammunition for this weapon are generally easier to locate throughout the entire game relative to Rockets, Ammo Belts, and BFG Cells, and are particularly abundant in the EnPro facility.

Tactical Use
The Plasma Gun is a very powerful medium to long range weapon; making it comparable to the higher-end weapons such as the Chaingun and the Rocket Launcher. It has a high firepower, a good rate of fire, and superb accuracy. Even stronger enemies like the Mancubi, Revenant, and the Hell Knight can instantly be incinerated by the plasma bursts in a matter of seconds, provided if the shots all connect. The Plasma Gun is also effective at destroying enemy projectiles as each shots create a "flak zone" to eliminate the Revenant's and Mancubus' projectiles in-flight.

The weapon's primary weakness is the slow speed of the projectiles, traveling slower than the shots fired by both the Chaingun and the Machine Gun. The slow speed of the plasma projectiles means that flying monsters, such as Cacodemons and Lost Souls can most likely avoid the plasma shots by moving to the side, before it hits them. This can be problematic if you were to fight against a swarm of Lost Souls at a close distance, as these monsters can attack very quick and sudden. Make sure you can connect your shots accordingly when facing these enemies. Alternatively, it is best to use Machine Gun or Chaingun due to the weapon's quicker projectiles.
