Halcion MK299

"Oh yea, that's right, we made a comback!!" - Moxxie (2059)
''The Halcion MK299 is a prototype version of the perfected MK300 Halcion Canon later on in the Saga. It is used during the counter-strike on the Destroyer Planet to tear several Plasma Tanks to pieces all at once. It is weilded by the new, perfected version of the Mech that Kevin used in 2029. It has the power to destroy continents if it so pleases and easily tears through the Destroyer fleet. ''

''This is an enhanced version of the MK299. It is a three-barreled Gatling version, able to tear apart literally everything. This is only used once during the very end of the Destroyer war. (It stands for: Mark 299 - Automatic Three Barrel)''
