Well i got to play online for the first time for MPO+ today. It was amazingly fun and a lot more than i expected. I was using my soldier with an s1 in pistols and the SAA and dominated that way. It was alot of fun. But i saw a couple soldiers that i knew nothing about. I saw a character dressed up in naked snakes clothes, but he had a bald head with spikes sticking out of it! Wtf? anyone know who that is?

And i saw characters with what looked like machetties (idk how to spell it) killing everyone. Does anyone know who these people are and how i can get them?

I take it you never got Metal Gear Solid Portable Ops and played the game? Plus is just an expansion. The original is the one with the story in it.

Anyways, the soldier with spikes is Python, a boss from Portable Ops and the one with the machette was Null, a second boss from Portable Ops.

Go buy Metal Gear Solid Portable Ops and play the single player. It is a canon part of the Metal Gear Solid story.
