This small Demo map is set in TDM mode, but, can be used in all other maps.
You will need to alter the player start marker to suit your mission type.

Look out for what I have changed..pay particular attention to the type of helo.
fblkhawk - indestructable blackhawk with 2 miniguns, I used this because it's the only helo you don't need to jump into, just run straight into it.

I also changed the default AI text file for the Helo -- from Helo - Blackhawk (transport) to Helo - Blackhawk Z ignore enemies.

Changing the text file means you don't need events to make the helo climb to the height of each waypoint, or events to make the helo follow a waypoint.

Make sure your waypoint list loops for this mission.

Look at the reset event times carefully.

Look at the Area Triggers carefully..
