Infinite Save Games
If you need to save more than once in a mission, then you need to delete the old save game file. It can be found in the directory Users\SavedCampaigns1985. ALT-TAB out of the game, make a backup copy (trust me!) and then delete the save file. ALT-TAB back and press ESC to pause the game. You should now be able to save the game again. You can do this as many times as you like.

Full Ammo
On the second level on campaign mode when your officer shouts go go go! Immediately type in moreammo and you will get full ammo.

Unlimited Ammo (Hex Method)
BACKUP FILES BEFORE PROCEEDING!

To alter the amount of ammo available to each weapon or magazine simply edit the weapons.cfg file found in the 'saved' folder contained within your user folder.

..UsersNAMESavedCampaigns1985
or
..UsersNAMESavedMissions1TakeTheCar

* Save a back-up copy prior to changing !!!

The weapons.cfg file defines weapon classes where u can change the ammo amounts.

class Magazine3
{
type="M16";
ammo=30.000000;
reload=0.133733;
id=352.000000;
};
class Magazine4
{
type="HandGrenade";
ammo=1.000000;
reload=1.215374;
id=353.000000;
};

Once changed you will need to re-start your mission or continue your campaign for the changes to take effect. These changes are often reset at the beginning of new missions/campaings requiring you to alter the new cfg file for that particular mission.

Bonus Level
After you beat the gamem watch through all the credits and let it go through all the loading screens. After the credits are over it will start a scene with the black ops guy talking on the phone to Dave (Armstrong, the inf. guy) After the scene you get to fly a Cessna into the Everon airport and pick up all the other characters that you got to play and take them to a pub.

Set the system date to December 25 and start the game. All of the pine trees will be covered with decorations and have presents under them.
