if you believe you are fast enough then try run thief run. ;)

The normal mission failure cut-scene is played after Trickster finishes the ritual. I didn't have proper codecs installed so that's why the failure theme didn't record to the alternative end video.

what happens after the video ends? is there a different cut-scene or just the typical skull sign that appears when you lose?

The unlisted feature seems to have bugged on that video. Now it should work since I changed it as public video.

hey man I cant see the alternate ending video, did you remove it?

The Trickster doesn't have melee attacks since he's a caster. He can cast web/swarm spells and when he detects you will get damage until you die. He has same alert system as other monsters so he interacts like assassins in map4. Similarly it's possible to walk behind him and hit him with blackjack/sword multiple times since he doesn't respond to that. I think that alert system checks difference in health and since he is invincible it counts as not detected. So he can only be alarmed if he hears or sees you. You can make him search you from the shadows ( http://www.youtube.com/watch?v­=Eo51RNuoIE4 ) but he will soon go back on his scripted sequence.

I uploaded the ending where you don't swap the eye:

Great Speedruns.

Just a question... What happens if The Trickster spots you? Does he try to fight you? I've seen a video of him just pointing at Garrett and then Garrett slowly taking damage.

Also is there an alternate cutscene if you fail to replace The Eye and he completes the ritual?

Thief gold has already been speedrunned by Simulation. Right now I can't find the site that hosted his files.

Great Thief speedruns, though is there any chance that there will be any runs for the Thief Gold exclusive levels?

Wow you are too l33t! Your runs are awesome. Im working on running Thief Gold. :)
