Creating Objectives
Objectives are the most important part of any Objective mode map. They determine how the gameplay should flow as well as setting winning / losing conditions for players.
Placing your First Objective
Open the Actor classes browser and navigate to StoryObjectiveBase. Expand it and you should see 'KF_StoryObjective'.

Select it and right click anywhere in your map with solid ground. You see the option to 'Add KF_StoryObjective'. Select this option and you should now see a green icon with a checkmark in the viewport.
