Chainsaw (Doom 3)

The Chainsaw is an extremely powerful close-quarters combat weapon, based on the classic weapon. The chainsaws in the game were sent to the Mars Base instead of Jackhammers by the Mixom Corporation. Humorously and ironically, in PDAs, many coworkers discuss how useless chainsaws are on Mars. It's the game's most powerful melee weapon first found in Service Room 2A of Communications Transfer.

Another melee weapon that deals out damage fast and stalls the enemy. Effective on almost every target give enough health and armour, with the berserker powerup boosting the weapon's power. Is considerably more powerful than its classic counterpart. Not available in PC Deathmatch. In Xbox DM it replaces the plasma gun.

Tactical Analysis
The chainsaw can be used as a last ditch attempt to survive when out of ammunition or as a means to dispatch zombies due to the fact the weapon has infinite ammunition like its classic counterpart. Usage on powerful enemies (such as (Pinky) Demons, Mancubi or Hell Knights) is not recommended as they will counter-attack the player, potentially causing heavy damage.
