i finally found a video store that hire this game out
what is the deal with the first person camera
is there a setting that i can change to keep it on fp camera
or is it the same R1 as mgs3
im a little confused

Hmm, I don't really know what you're trying to say. To go into first person view in Subsistence, it's R1, same as Snake Eater. There is no FP mode, you may be confused with the new third person camera, which is in a lot closer and can be moved with the right analogue stick to see all around you. Also, pressing L1 with this camera will point it behind you, a quicker way.
Pressing R3 no longer locks the camera in place, but instead switches it from SE cam to Sub cam.
SE cam works same as usual, just without the locking in place. You will start a new game on Sub camera, I believe, if that matters. That should hopefully have cleared things up for you.

oh okay
i think i understand now

i thought there was a new fp camera mode which makes the whole game
like an fps game instead of having to push R1 all the time

the new 3rd person cmaera is quite handy though

There will be a FP Mode in MGS4, but in Subsistence they were only experimenting with the third person camera, instead of the usual "looking down on Snake/Raiden" camera that's been in every MGS game up till this one.
