Temple Assembly Site
Glitchless :
Strat A (1st entering of the room) :
There is a point at the left wall that you immediately want to hit (shown in the video) which triggers the "Temple Grounds cutscene" .
It saves about 2 seconds.
After that you immediately scan the scanpoint and jump/move to the door.
Strat B (Entering after Dark Alpha Splinter) :
Scan the blockade, jump over it, shoot a missile at the red door before you enter the cutscene (not during because it would negate the missile completely)
When you get to the cutscene you will spawn directly before the door if you go the right way instead of the left way.
After you got the energy tank you just go to the door.
Strat C (Entering after finishing Agon, Torvus Bog, Sanctuary Fortress) :
After you entered the room you shoot the dark crystal and then roll/springball your way up to the transporter door.
After you finished Torvus Bog or Sanctuary Fortress you go through the portal.
It is recommended to open it directly after Agon.
