ok , but are there any sniper codes ?
they are really hard to find!
It's not even close to be hard to find them because every item type has it's own id area. For example the nades are around 2800-3040 or the rifles from 1600-1800 and sth like that. If you know what you search for it's very easy to find the items but there are currently no snipers to add for free.
