When I got 60/50 achievements in Oblivion.
Also when I was playing Earth Defense 2017 with my neighbor. We were standing side by side with machine guns. Soon I realized there was no way we were going to survive. So to save myself I ran behind him and shot his feet with a rocket Launcher. After that all the ants swarmed him and I continued to pelt him with rockets... I won the fight but it was at a great loss
