Chaingun

The informally styled "Chaingun" is a weapon recently seen about twenty-four seconds into the Halo 3 ViDoc: Is Quisnam Protero Damno!. Although the weapon will presumably appear in Halo 3, little is known about it at this stage.

Advantages
Due to its high rate of fire and apparently high damage rate, it seems likely that this weapon is deadly to anything which is in range for a clear shot.

Disadvantages
Unknown. However, there must be certain crippling disadvantages, or its user would be unstoppable in combat. Some have speculated that it will slow down its user considerably; others claim that it could only be used for a limited time before 'dying'. Its true weaknesses are unclear.

Appearances
This weapon appeared in the Halo 3 ViDoc: Is Quisnam Protero Damno! This suggests that they will be seen in Halo 3, although they have yet to appear in any other medium.

Behind the scenes
When this weapon first appeared in the ViDoc, some believed that it was the M41 LAAG from the Warthog. However, it was eventually proven that the new gun, dubbed the "chaingun", was different in appearance. Recently, Frank O'Connor went on record as saying that the turret could not be removed from the back of the Hog. However, this was repeatedly analyzed by fans who concluded that this did not actually confirm that the chaingun was not the M41 LAAG, despite evidence to the contrary. Until more can be discovered about it, the chaingun's true identity will remain an enigma.
