Master Chief Escape Plan 

When one utilises the battle tactics and escapology of the Master Chief from the Halo series.

This can be adapted to many games and involves the player shooting anyone who gets in his way, whilst running like a bitch to get somewhere safe, or to an evac. point.

This technique can also be used in conjunction with Master Chiefing It
