Did you think the Hellions had run off after being routed once? Oh, heavens no. Here they are aga--
Something's not right here. The only two people who own those types of mechs that aren't Hellions are Caleb and Amelia, and neither of them is present. There appears to be infighting going on between the Hellions, as shots ring out. One goes down, its leg sheared off by a gauss slug, and it looks up at its aggressor.
Who proceeds to shoot the downed 'mech directly in the head. Anyone who is familiar with them or knows their style knows that this is generally not their style, and given the chance they will capture downed foes rather than kill them.
Another stops moving after its head gets torn through by a bolt of blue, searing energy."Nexus denizens, you seem to have caused a crisis of faith in some of our soldiers. They have been summarily executed and those who are more loyal put in their place. Any more attempts to engage us in non-conventional combat will result in the same."
"Now defend yourselves."
The mechs that remain begin to open up on pretty much anything or anyone nearby. It can be assumed that this area is an AVF free zone. They're not even trying to discern between combatants and noncombatants anymore, unless someone is flagrantly a noncombatant.
EDIT: things have happened
