Metal Gear Solid: Portable Ops/Headscratchers

• In Portable Ops when Ocelot talks to the DCI about the Philosophers Legacy, he says he has come for the other half. Now in the Metal Gear database its mentioned that the DCI kept the half of the Legacy obtained by Naked Snake and declared Snake Eater a failure. So where did Ocelot(and Zero I guess too) get the other half of the Legacy from?
  • He no doubt spent the time between 3 and PO getting his hands on the Russian half of the legacy.
  • I thought that the info on the Legacy that EVA took in Snake Eater was fake, and taken by Ocelot? That's what I remember happening.
• In Portable Ops the ICBMG is launched like a missile and para-drops to it target and then launches it's payload. Metal Gear RAXA was a test version of the ICBMG and required a pilot to operate. There is no mention of AI in Portable Ops, does this mean the ICBMG also requires a pilot? If so who was operating it when Gene launched it?
