Tracking:

Press Alt + F1 to go into Virtual Pilot mode, then J to enter into padlock mode. Wherever the bandit goes, your view will track him.

Cheat Mode:

Type RASTA and the cheat mode will be enabled.

Raise altitude:

It's possible to make your aircraft invincible in the controls. When this is on, press Ctrl + Tab, your altitude raises with 500 feet.

Slow Motion:

While in flight (or after you die), you can hit + + S (the keys + > S ) to go into slow mode.

Move the plane like you want it :

You start out in the exact geographic center of the island. No hit [+]-[X] to turn on your joystick. Now, you can move (point) with your stick.

Here are the keys:

Hit [8] repeatedly to go forward.
Hit [2] repeatedly to go backwards.
Hit [4] repeatedly to go left.
Hit [6] repeatedly to go right.
Hit [7] repeatedly to go up.
Hit [1] repeatedly to go down.

The trigger fires the cannon (toned-down for some reason) and fires heavily toned-down mavericks.

Now you can visit the baseball field in Havana, the hole in the wall or complete the mission after you die
