Ooh er...
I can't help but feel that Ocelot would betray me at every possible moment.
Raging Raven would still come in handy (she can fly and has missiles and a grenade launcher that fires explosive, incendiary, flashbang or smoke grenades), and if Ocelot did fight for me, then he'd be awesome. He has a very powerful single-shot pistol, and is just as good as Solid Snake at fighting hand-to-hand.
Oh, and there's a Colt SAA in my avatar (the R in Redingold) so Ocelot could use that. Or I could, but I'd rather let Ocelot do the shooting, given how he's good enough to kill everybody in a room - with the same bullet.
Oh, and if I get Ocelot, does that mean I get Outer Haven too? And the 5 largest PMCs on the face of the Earth? And a sweet-ass battleship with stealth nukes?
