The example mission is to help you learn the key things of mission making. Like:
Dialog
Working with Zones
And a basic vehicle ambush.
Please use the editor to play the mission, as the in-game one may or may not crash. This mission is to assist you in learning a few things but also to let you experiment with things you learn here. The mission is very very small and basic but it will give you a few pointers if you study the triggers carefully, the mission will be updated quite frequently with new things added in. If you need any help or any suggestions/bugs please let us know in the comments :)
