Game archives vary wildly and you usually have to rely on a third party tool (like OpenIV) or try to document it yourself, usually by using a Hex Editor and studying the code to parse the files. Once you know what to patch, you could just write a small C++ library that scans the game's memory for the location to patch and then applies the patch. For static analysis you could use Ghidra (free) or IDA Pro (very expensive), but I'd recommend starting out with just Cheat Engine initially. A more powerful debugger would be 圆4dbg (which is free). Cheat Engine is a great tool for that and all you really need initially. From there on, by setting a breakpoint on it, you can find the code that modifies it and for instance NOP it so that it no longer does anything. This process will (usually) allow you to find the address in memory that stores the ammo count.
That sounds a lot like memory scanning for an unknown initial value, then looking for a decreased value etc.
