Counter weapons: Sniper weapons (sniper rifle, Beam Rifle), carbine, SPNKr, and Fuel Rod Cannon.
The plasma Rifle also ha the ability to slow the running speed of a target in Halo 1. while firing at them they would walk slightly slower. also grunts and jackels are "Not worthy" of the use of a plasma rifle. they are not ever givin the chance to use one. Lt.O'Brien 17:59, 8 January 2007 (UTC)

- No need to worry. I understand Halopedia articles are to be named by their official UNSC designation even if there is a more common nickname and the majority of people are unfamiliar with the official name.

Discovery of weapon by the Covenant
Has anyone noticed how similar these are to those "constructors" that build/repair on the Halos and the Ark? Don't you think the Elites likely just found a still-running Forerunner facility on some planet, had their Engineers modify the constructors to Elite tastes (and remove the AI and flying ability, of course), and mass-produced them as plasma rifles?

Underpowered on halo3 multiplayer
This article makes no mention whatsoever on how little damage this weapon does to unshielded players compared to its predessors. It even says its more powerful under the halo 3 section!
- The article DOES mention that this weapon makes very little damage to flesh. It says its more powerfull AGAINST shields Daniel 019 21:52, 7 April 2008 (UTC)
Masers?
In the trivia section, there is a mention that masers are used to generate plasma. Surely this is in conflict with the main article saying that it uses electric arcs to generate plasma? Where did that piece of information come from anyway? I didnt see it mentioned in any of the references. Diaboy 09:12, 15 May 2008 (UTC)
i would just like to say
that the plasma rifle is a unique symbol of the trilogy and it is instantly recognisable by its look and sound. i love this gun it reminds me of when i first played halo 2
