Before the alien raiding fleet had arrived at the crucial planet, the human defenders had already entered into complete disarray!
All of the mech pilots and other personnel of the Grimly Brothers had turned their weapons against the other mercenaries assigned to the same defense mission!
The Grimly troops that previously appeared friendly and easy to talk to had cast aside all joviality and tried to murder as many humans as possible!
Despite being heavily outnumbered, their sensitive positions and their abundant preparations caused their opening strikes to inflict devastating damage!
On the surface of the planet, plenty of mech hangars, weapon depots and defensive works blew up in short order!
Squads of melee mechs in Grimly colors dashed into the exposed formations of ranged mechs and cut them to pieces without mercy.
