688 Hunter-Killer cheats and cheat codes for PC

Hexcheat:
If you open the player.db file a hex editor, you can edit your 
points. Go down to offset 2544, then enter the value 286B. This 
will give you about 27,400 points to start your captain with. 
It should give you all of the possible sub improvements and leave 
about 7000pts. to put into your crew.

This can be done before you begin your first mission. All you have 
to do is create a captain, and then exit the game without choosing 
a mission. 

You can use the cheat again after your first mission to get 
another 27,400 pts. but you will only be able to use about 5000 
to max out your sub and crew.
