Not sure if I understand what's the deal but let's have a try...

This is some i would need:

R.U.S.E on hardest difficulty and all operations done, EU.
Under siege, save on hardest difficulty, EU.
Bonic Commando, save on hardest difficulty, EU.
Rag Doll Kung Fu Fists of platic, with one gold medal missing (prefarably Capture the fish or King of the hill they are the easiests). US
Scourge Outbreak 100% save. EU

These are saves I couldn't find anywhere, or were deleted without any traces. If you ever had any, that would be so great.

^ This guy knows what the fuck is up, those are great requests.

I'll add

Bionic Commando Rearmed - either a beaten save file or the hardest difficulty unlocked from the start, or all challenges done. The 100% save on gamefaqs doesn't unlock anything.
Hoard - Anything
Soldner-X
Soldner-X 2
El-Shaddai - Non 100%, 9/10 G ranks preferred, anything is ok
Bioshock Infinite Modded - the save on here does not give trophies
Metal Gear Rising - dead saves on this site
Renegade Ops - Hard save, save on this site does not work
Syberia II
Under Siege - Anything

I hope we're not asking for too much, but these saves aren't on the site and there's nowhere else left to go

about Metal Gear Rising,I found a platinum save set here:
You must login or register to view this content.

I checked,the save is working.

HI, i need:

SHANK 1
RENEGADE OPS + DLC

Command and conquer red alert 3. Hard mode saves or anything that'll get the online map wins done

You mean you can get any save? Heres some:

Command and Conquer Red Alert 3
Twisted Metal
Stormrise
El Shaddai
Starhawk
R.I.P.D The Game
Rocket Knight

Command and Conquer Red Alert 3 Hard EU - i play it and only 2 Missions left.... PS3 kills the save... I will not start again...
Greg Hastings Paintball 2 EU
Badlands EU
Syberia 2 EU - is there a chance with a hack save to unlock the bug trophy
