The Mega Mech was largely unseen through most of the war, and has only recently started engaging the Global Resistance. They are usually reserved for species more advanced than humans, but due to the continued success of the human forces they have been put to use. They are first encountered by the Second Mass during an otherwise normal resistance raid, despite initial success the resistance are ambushed from behind when two Mega Mechs emerge from the ground and attack killing multiple resistance members who's weapons have no effects on the Mechs. They are saved however by the timely arrival of Tom and Cochise who destroy both Mechs with repeated hits from their Volm-tech weapons. Mega Mechs seem quite rare but become more common as the series progresses. (On Thin Ice)
Like standard Mechs, Mega Mechs were created by the Espheni and have likely been used in battle against other alien races such as the Volm, explaining their familiarity with the Mega Mech.
A Mega Mech is twice as tall as a regular mech but contains the same metallic color as a mech. The Mega Mech is much more powerful than a regular mech and much harder to destroy. It has the same bipedal stature as a regular mech but is overall far more menacing in appearance. Standard mechs only possess one gun-arm, the other arm ending in a manipulator-hand so they can be used in scouting missions. Mega Mechs, in contrast, possess nothing but guns at the ends of each of their arms - they are designed for pure combat. They are equipped with two shoulder mounted plasma cannons and two on their lower "arms". A third set of "arms" located in between the cannons are used as rocket launchers. Some Mega Mechs are capable of switching from plasma cannons to flamethrowers. (Ghost in the Machine)
Two of the arms can be folded into their backs when in transit-mode. Mega Mechs also have a clearly defined humanoid head, which standard Mechs do not possess, perhaps indicating a more advanced sensory package.
Combating Mega MechsEdit
The Mega Mechs are easily destroyed by Volm-tech augmented guns. Tom Mason and Cochise were able to quickly dispatch a pair of mega mechs using their augmented guns. Before they came, the humans were having problems combating the mega mechs. They suffer from the same AI failings and slow targeting capability as the regular Mechs. Despite their weakness to volm weapons Mega Mechs seem completely invunreble to human weapons, even a 50. calibre HMG seems to have no effect on then. They seem to rely more on sheer armour and firepower then speed or intellegence though are to jump long distances when the need arises.
- Yahoo TV announced in a video that in the third season of Falling Skies, a new type of mech would be released.
