In a game of Halo 2 or 3 when in a situation of two on one where players A and B are on the same team and X is on the opposing team. Player A engages in a fire fight with the opponent (player X) lowering their shields substantially and in the process losing most or all of their shields. Before player A is killed he retreats into a room or cover and player B emerges a half moment later. Player X believes that he is being faced with the same enemy and moving in for the kill. In reality he is at a disadvantage and is killed by the fully shielded player B.
I thought that guy was either being really brave or really stupid, charging back out after i had his shields flashing....turns out it was a different guy. I got bait and switched.
