U wanna beat him easy then? save the game during the fight, then forward the ps2 date by 2 weeks, then load up the game and a cut scene will play in which snake finds the end and tells him to drop his gun, he dosen't snake pushs him from behind, and THE END falls over dead, when snake turns to leave, THE END'S body blows up.
