A Greater High
Before the War General took up its Destroyer Axes, the mech employed an unusual ranged weapon module, turning it into a marksman mech.
Waltz eventually abandoned the strategy seeing that his War General would exhaust its energy reserves long before the Ouroboros succumbed from the damage. Yet even as the mech pulled out the hollow shaft from its chest and turned them into compact handles for its Destroyer Axes, the weapon module in its chest still existed.
Even though retractable armor plating quickly closed up the hole in its chest, it still represented a structural weak point in the War General!
Even in this form, the War General was still very much a multipurpose mech! Although Waltz abandoned all other modes of attack in favor of overpowering the Ouroboros with an unrelenting rain of axe strikes, those other modules still remained in place!
