Service history

In service:


"[The plasma pistol] is the bread and butter of Covenant small arms—almost as common as the MA5 is with the UNSC. After the Covenant Carrier jumped there were some areas of Mombasa where plasma pistols covered the ground like leaves—that maneuver killed a bunch of dudes on both sides."
— Anonymous UNSC E2-BAG/1/7 serviceman[5]

The Eos'Mak-pattern Pistol (UNSC Type classification: Type-25 Directed Energy Pistol, T-25 DEP)[2] also known as the plasma pistol,[5] is a Covenant infantry weapon originally manufactured by the Assembly Forges during the Human-Covenant War. Following the Fall of High Charity, the plasma pistol is manufactured by Iruiru Armory.[4]


Design details[edit]

Main article: Plasma pistol

Manufactured by Iruiru Armory, the Eos'Mak-pattern plasma pistol is a directed-energy weapon employed by the Covenant and its splinter factions. The Eos'Mak-pattern was the most common variant of the plasma pistol, often utilized by the frontline infantry like the Unggoy, Kig-Yar, and Yanme'e.[4] However, the design pattern is associated with an innumerable different sub-classes, much to the consternation of UNSC intelligence officers tasked with categorizing new variants.[3] Certain sub-variants are equipped with tracking sights.[2]


The Eos'Mak-pattern was the most common variant of the plasma pistol, employed across the Covenant and its splinter factions. It was commonly used by members of the lower caste, such as the Unggoy, Kig-Yar, and Yanme'e.[4][8]

Non-canon and dubious canon appearances[edit]

Nice opinion, but unfortunately you're an Elite preferred species.

Eos'Mak-pattern plasma pistols are used by the Covenant against humanity.[9][10]


  • In the PC version of Halo: Combat Evolved, if the player has a modified controller with rapid-fire functionality, they can fire the plasma pistol as fast as the second highest turbo setting, which is as fast as the assault rifle. However, it overheats extremely fast.
  • In the Halo trilogy, if the player's plasma pistol is running low on battery, (less than 10%) when they fire it, then it will occasionally splutter and refuse to fire. This may be due to the fact that the power cell is unable to focus the remaining energy into a ball of plasma.
  • After killing the Prophet of Regret on "Regret" in Halo 2, he will drop a plasma pistol. He held the same weapon in Halo: Contact Harvest, and was rumored to keep it with him at all times in Halo: The Cole Protocol.
  • In Halo 2 for Windows Vista, it is possible to instantly destroy a Karo'etba-pattern Ghost by aiming an overcharged bolt at the metal flaps on the back of the Ghost's wings.
  • In Halo 2 for Windows Vista, if the player is carrying the plasma pistol and are in active camouflage, one may see a polygon near the front of the weapon. In Halo 3, while using active camouflage, one can see a square where the heat monitor is. This indicates the hologram is a polygon.
  • In Halo 3, if the player overcharges the plasma pistol and slowly release the trigger, it will not fire a shot. The plasma would slowly dissipate and disappear. This can be used as a way to prevent excess battery depletion when an overcharge shot is fired. The plasma pistol in PC versions cannot do this as the player is using a mouse to control the firing.
  • In the "Extras" section of the Halo 3: The Official Strategy Guide, it is stated incorrectly that the plasma pistol has a clip size of 10/100 when it does not have a clip size at all.
  • In Halo 3, it is the only dual-wieldable weapon that does not cause less damage per shot when dual-wielded than when single wielded. (26 head/body shots single- or dual-wielded to kill with normal shields; as compared with the M6G that takes 5 head or 8 body single-wielded but 7 head or 11 body when dual-wielded).
  • In Halo 3, if one looks at their shadow whilst holding a plasma pistol, one may notice a "cap" like protrusion on the back of the gun. This is actually the hologram on the gun that indicates if it is overheated.
  • In the Halo: Reach Multiplayer Beta, the sound effect for an overcharged blast was the same as when a circuit is hit in Marathon.
