Yep, Miss Alenko is at it again, taking a trailer and watching it several times, trying to study it frame-by-frame (to the best YouTube allows) and taking everything to have some sort of meaning to it.

Perfect Dark XBLA Trailer http://www.youtube.com/watch?v=U4fw0VvPg9w

0:15-0:34 Much like the original opening for the game, Perfect Dark shows the developer & producer logos come in the same way, with 4JStudios (the new developer for Perfect Dark) transforming into the Perfect Dark 'N' much like old developer Nintendo's logo did.
0:35 The opening cutscene for the second level of Perfect Dark
0:41-0:42 Cutscene from the third mission 'G5 Building'
0:46-0:48 From the game's opening cutscene from the first level, mission 'dataDyne Defection'
0:48-0:52 Sniping to protect the 'negotiator' from the second mission 'Carrington Villa'. Notice that the way the sniper zoom doesn't differ from how it zoomed in the original.
0:52-0:53 dataDyne/Skedar assault on the Carrington Institute from the seventh mission 'Carrington Institute'
0:54-0:55 Taking out an enemy who can use a cloaking device. Notice that the cloaking device still has a blocky aura around the user. From the third mission 'G5 Building'
1:00-1:01 Entering the sub from the sixth mission 'Deep Sea'
1:02-1:03 The Mayans attack the Skedar in the 9th mission 'Skedar Ruins'
1:04-1:05 Elvis taking over a Skedar ship in the 8th mission 'Attack Ship'
1:06-1:07 Joanna rescuing Elvis in the fourth mission 'Area 51 Escape'. Also, you can clearly hear her say "I don't care much for procedures" using the original audio files from the original Perfect Dark, minus the audio grain.
1:07-1:08 Eliminating Skedar in the 9th mission 'Skedar Ruins'
1:13-1:14 Classic 4 player split-screen multiplayer. Upper left is using a Mauler, upper right a Super Dragon, bottom left dual Maulers (secondary fire mode as indicated by the yellow box) and lower right a rocket launcher.
1:15-1:16 The multiplayer mode where one person tries to complete the mission (having only life but a large health bar) while the other player tries to stop them (having unlimited lives but a small health bar.) as seen in the 1st mission 'dataDyne Defection'.
1:17-1:22 More multiplayer action. Notice that at 1:22 for the upper left section the message 'Killed MeatSim:1' pops up, showing the return of one of the classic Sims from the original game.
1:27-1:28 The classic 007 Goldeneye multiplayer map 'Facility' remade in Perfect Dark as 'Felicity'
1:28-1:29 More gameplay from the first mission.
1:30-1:32 More Facility/Felicity map gameplay.
1:33-1:37 The use of full team colors has returned.
1:39-1:41 Again, using old audio files (minus the grain) you can hear dataDyne CEO Cassandra De Vries say 'Goodnight Miss Dark'

If I muffed up on the missions, I'll be sure to fix it later.
