You can use the Userdisk (ar any formatted disk) to save:
Snatcher controls are the usual on Graphical Adventure games. You should use the keys 0 to 9 to select an action.
After you receive Metal Gear, you will be able to save a game, using the normal menu system (following the options: ).
SHIFT may be used for two things in the game:
- point your gun
- move Metal Gear's light.
In both cases you'll need to push (and keep) SHIFT key, and then select the area where you want to shot or point the light.
User Disks are just normal 3 1/2 DD formatted disks with save games on them
