ACS

"The ACS. It stands for an armored combat suit. These guys are so cool that I think they're so deadly that your life can betted upon."

--Su Ji-Hoon, Miles' Future Days

An ACS (which stands for an armored combat suit) is a machine that will kill anyone on their path. First, it has a really strong armor and a damage rate! It's really hard to kill, and it also shoots really fast, so enemies will have to watch out for this killer.
