Big Boss Emblem MGS4

I'm not really good at hardcore difficulties on games, my reaction time can sometimes be slow. Anyway, i would seriously love to get Platinum on MGS4, granted it will take time as i hear you have to play the game countless times to get them all.

Anyway, i plan on giving it a go, i do have a couple questions though

How many times can you save on BBExtreme, i hear on MGS2 you could only save 8 times altogether

Can you use the Facecamo during the game

Are the bosses easy, i sometimes struggled against Vamp now and again even on easy.

Are there any items/emblems i need to get as well on BBExtreme apart from the Big Boss one itself.

Do i have to collect all the Ipods again that i got in the other difficulty or will it not matter as long as i get the 2/3 that are in BBExtreme difficulty.

I think thats it, i hope i explained it well :D

you can save as often as you like but you have to finish in under 5 hours

pretty sure you can still use facecamo but it 's been a while

there are pretty fullproof strategies for most bosses so yeah i guess so

don't think so but you'll get fox emblem and such anyway

nope it all carries over

the minimum amount of playthroughs for platinum is about 8 i think, good luck anyway i had a blast getting it
