Joshua took down the enemy rifleman in one shot. The knight endured three more shots but fell after suffering another. The isolated artillery mech panicked after losing its companions and scurried back to base as fast as possible.
Sadly, heavy mechs tended to run at a crawl. Despite its lack of escorts, Joshua prudently slipped away. He shot five times in a single engagement and built up quite a bit of heat. His mech's internal heat sinks absorbed most of the heat so far, so his mech maintained a low profile.
"All of that heat will spill out if I stress the Old Soul's heat capacity."
The mech came with a very loud warning to never exceed this limit. Even if he had to let go of a juicy target, Joshua pretty much had no other choice.
He bunkered down his mech and waited patiently for the heat to disperse. Even as every other mech threw themselves into battle, the Old Soul stood as rigid as a statue, as if it knew its time hadn't come.
