Progressing Too Fast
As the fight began to get hotter and hotter, the amount of casualties suffered by both sides increased at a faster rate.
Surprisingly, the amount of lives lost by both sides were fairly tame.
Many of the combat carriers of the Hex Army and the Golden Skull Alliance were already being run by skeleton crews. If the starships suffered so much damage that they no longer became operable, then a small number of crew members could still evacuate with ease.
Even the artillery mechs stationed inside the bunkers still had a way out. As long as they managed to flee in space, they could rely on standalone floater modules or other auxiliary flight equipment to continue their participation in battle.
Of course, these exposed artillery mechs attracted a lot of enemy fire as well. Their large size along with their awful flight characteristics in space meant that it became easy for mech units such as the Blackened Reapers to demolish their frames!
