The year is 2055, more than thirty years after the events of Zero Hour, Earth suffers a catastrophic collision with meteorites. The world is thrown into turmoil as large swathes of land are annihilated. Four factions, the ADF (Asian Democratic Federation), WEA (West European Alliance), WLF (World Liberation Front), and AC (American Confederacy) are at war for control of the remaining already harder to find resources as well as the preservation of their nations and geopolitical interests. Welcome to Deep Impact.
The first, and least expensive modification that the MRC can be fitted with is fittingly named the Protector. A close air-support weapon, the Protector modification adds an additional two chains guns to the MRC, allowing it to shred enemy infantry on the ground in seconds. Further, due to the enhanced heat from the three guns firing synchronously, enemy armour also takes a reasonable pounding. This modification is useful for making the MRC a multipurpose platform; in that it is a jack-of-all-trades, but a master of none, bar gunning down infantry. Should you want something more specialised, the Railgun modification may prove more fitting.
3 gatling cannons, ground infantry is totally screwed
Is it possible to make all 3 chain-guns capable of separate targeting?
I would add blue tracers in the animation. Or make it a plasma cannon.
