Confused about MGS? well I was too, but i have finnaly worked it out. here goes:  Solid Snake(David,Pliskin)  Relatives: Big Boss (solidus snake, Naked snake) Father LiquidSnake Brother. But also there is Raiden whos parents apparently died and was adopted by big boss which suprisingly makes Solid Snake, raidens step brother.

Also a lot of people are confused what snake is in which game well: Solid Snake is in MGS1, MGS2, MGA, MGA2 and is coming backed aged in MGS4. However Big boss is the Main character in MGS3 and will also be in MGS Portable OPs (set 6 years after MGS3).
