Over-scope is a battling "phenomenon" that can occur between two robos. It entails a robo missing its gun shot at very close range. Normally, at close range, two vulnerable robos would ready themselves for an unavoidable damage-inflicting shootout. However, it is possible for the gun round(s) to totally miss, even at almost point-blank range. The probability of this event happening depends on the velocity and movement angle of both robos at the instant of round impact as well as the round size(s).
