This is table for both games. I used GOG version for the first game and Steam version for the second.
In first game I could have not merge properly two ammo scripts, so I left them separately - activate "ammo" first and then "ammo shotgun". In second game ammo values are bit weird, so I have made "no-reload" script instead.
Hope everything works.
