i think P2 just used a little drop pod thing as the AVP preds did? he returned to the larger ship at the end, i did always have the impression that P2 was a bit of a bad ass though, more so than the P1? who knows, i think its certain already that the Wolf is the man though, no trainee atleast...

I alway's thought of the P1 as being an experienced hunter, he gets left alone on a planet to hunt, treat's his wound with what he's got on him, polishes up his trophies with his gear on hand.He dosen't get involved with the firefight between humans, he just wait's to see who the bigger challenge to hunt will be. The P2 was a sloppy hunter, and I think he was on his first human hunting trip with the elder and the other preds from the end of the film( he left his spear tip behind, he kept going back to the same warehouse to eat, allowing a trap to be set up for him, he went nuts in the subway,in the hotel, and in the warehouse, killing lower class prey, but then only taking the one trophy.) He went back to the ship to polish up King Willie's skull and mount it, so I don't think he came down on his own.
And the AVP preds, well these ones were pretty much newbies. Full armour, all brawn, no brains. Scar was promising, but made some big mistakes, and failed his hunt. I'm just surprised that the elders showed him any respect at the end, he didn't even sacrifice himself when he let his wrist nuke go, he ran away.
The Wolf, I think he's even more experianced than P1, but we shall see.
