This events below shows how to spawn a single destroyed AI or a group, and how to teleport them
alive into the map again. To the location that you and your teammate have not reached yet.
__________________________
Trigger Timeline.
When you shoot a single ssn or a group, it will lay dead there for 28 sec.
And then teleports to a Tele-MARKER way off, still dead.
He respawns after 30 sec. 2 sec after teleport. /when I teleported the group after the spawn.
I could see him/them standing up in total before teleporting away. Not pretty!
When you, or your teammate later on triggers a designated area-zon for a fight. The teleported and now alive group will teleport to a second and final target.
__________________________________________
I belive that a large amount of ssn´s or groups that teleports
at once will create lots of lag.

------------------------
fair warning. I have tested this with good results.
Try to keep in mind that each group or ssn that teleports/respawns need his own final teleport-marker.
