Cheat Engine

[Major Tom]

Hello,

So I'm trying to hack this game with Cheat Engine.
The game has a system where you can buy weapons. The problem is, the money is not hackable, but the weapons are (so I've heard).

What I want to do is let cheat engine scan the game, then I buy for example the AK47, and I want cheat engine to pick up what value has changed by buying that weapon. Is that even possible to do? Or is there a better way? I'm just thinking out loud.

The thing I basically want to reach is being able to change the weapon value so it will turn into another weapon.

Thanks!
