Additional ammunition

Note: This procedure involves editing a game file; create a backup copy of the file before proceeding. Use a text editor to edit one of the "level_*" files in the game folder. Locate the "//Bullets, Projectiles, Missiles" section and increase the three numbers that follow the "Ammo" entry that is underneath to set the amount of bullets, projectiles, and missiles (in that order) that will be available in that level.

Change enemy aggression

Note: This procedure involves editing a game file; create a backup copy of the file before proceeding. Use a text editor to edit one of the "level_*" files in the game folder. Locate the "//Tank, Jet, HelicopterGun, HelicopterRocket" section and decrease the four numbers following the "Aggression" entry to lower how difficult the enemy tanks, jets, helicopter guns, and helicopter rockets (in that order) will be in that level. Note: The numbers must be from 1 through 9.

Tip:
If you're having trouble aiming, follow the path of your tracer fire or make your own crosshairs with Scotch tape and stick it on the monitor.

Tip:
Conserve heat-seeking missiles for either tanks or planes. Deal with helicopters with standard artillery fire.

Tip:
The only reason you should use your handgun is to pick off supply crates that drop in.

Tip:
Switch to the Antitank gun when the big chunks of metal start rolling in.

Tip:
Try to pick off enemy foot soldiers while they're still in the boat. You should be able to wipe out all of them with a direct missile hit.
