Hai friends,this is my first tutorial in DYOM,so there could be some mistakes in the text.

Ok to start the mission as a skydiver,make a player or actor that has to be a skydiver,then make a object like a gate,make it stand flat,and make it come down the actor or the player and make it go up in the sky,and give a parachute to the actor that stands on the gate that will be spawned in the sky,then make a time out objective(keep the time like 2 seconds)and make the object hide after the timeout session,that's all,it will be a sky diving mission from the start.
