    I don't know if you can edit the savegame to have unlimited ammo, this is how the shotgun entity looks like within a savegame:

    Code:
       <Entity id="2965">
        <EntityProxies>
         <RenderProxy />
         <GameObject numExtensions="1">
          <Extension name="Marshall" accAmmoAvail="1" m_serializeRigidPhysics="1" m_deferPhysicalization="3">
           <ItemStats dropped="1" brandnew="1" first_selection="1" pickable="1"/>
           <WeaponAmmo AmmoAmount="1" BonusAmmoAmount="1" minDropAmmoAvail="1">
            <Ammo AmmoName="shotgunshell" Bullets="10"/>
            <Ammo AmmoName="shotgunshell" Bullets="10"/>
           </WeaponAmmo>
           <WeaponStats />
          </Extension>
         </GameObject>
         <PhysicsProxy pos="246.60635,90.448433,46.862675" rot="-0.18809304,0.68163115,-0.18809304,-0.68163115"/>
        </EntityProxies>
       </Entity>
    I will also attach all profile files (profile.xml, attributes.xml etc...) decrypted.

    WOW! Thats good progress, so basically its 0 or 1 value to mod the save file.

    It's amazing how much Crytek has been working on making this game secure, i have spent quite some time on this but not only on the CRYe files but also on the .pak encryption and the online security.

    If nobody else is releasing a tool to decrypt / encrypt CRYe packages i will, but as of now i still need to fix some bugs and make sure my routine is correct for creating the real key from the raw key (yes, the raw key is encrypted aswell using a nifty scheme).

    I need to get the key for PS3 version, does anyone have the game excutables?

    Update:

    My tool is starting take shape, this is what has been done so far:

    * Key generation routine has been 100% reversed, now i can generate decryption keys from the key found in the executables, still missing the key from the PS3 version (and if updates)
    * Decryption routine is 90% complete, it can decrypt but sometimes spits out strange characters, easy to fix.
    * Encryption routine is 0% complete, i need to decrypt before encrypt ;)
    * Added the following keys to the application:
    - CRYePC1
    - CRYeXB1


    Output from one of my tests, aaah, nice strange characters...
    Code:
    38, 2nd: (ecx): 2f, (204h): 2f (S), (ecx): 45, (20Ch): 3c (S), (bl): 45 (G), (cl): 3b (G), (key[3c]: 45 (S), (key[2f]: 3b (S), (return: 5f)
    
    22, 2nd: (ecx): 30, (204h): 30 (S), (ecx): 26, (20Ch): 62 (S), (bl): 26 (G), (cl): 4d (G), (key[62]: 26 (S), (key[30]: 4d (S), (return: 85)
    
    2f, 2nd: (ecx): 31, (204h): 31 (S), (ecx): ae, (20Ch): 10 (S), (bl): ae (G), (cl): c0 (G), (key[10]: ae (S), (key[31]: c0 (S), (return: 57)
