The Last Stand: Union City

Most values in game are 4byte*8, health seems to change addresses a lot though (hoping for an AOB)
Works for ammo, clip ammo, both upgrade points (recommend leaving some room to upgrade stat points since if you max all at 20, you can't leave the upgrade screen until you use them (or make the value zero)).
