Killzone Liberation: Rare Codes

The only rare codes I have are Snap to player and a bunch of spidermine and flame color hacks.

I am really looking for the ones where you can put weird weapons in supply depots. The most common one I see is Knife, but I have seen a Grenade Launcher and the ISA chaingun. I have also yet to find a good REMOTE CONTROL ROCKETS.
Does anyone know where I can get these codes?
All help is greatly appreciated.
btw, if you want I can post my complete archive of codes I have for that game.
Thanks :)

tru!! iv seen ppl do that all da time if u guys get it please let me know also
