Removed-, unused- and forgotten models from way before release
Wednesday 9th of October 2013

Inspired by /u/WoodenPotatoes video "Guild Wars 2 in 2009" I decided to take a closer look at one special DAT file I've archived and tried to find things that have been removed before launch. To get things started I've extracted a large number of models, and tried to make them look pretty by manually shading them.

Players and NPC
Female Sylvari 1, 2, 3 One of the original Sylvari designs, just an elf with glued on leaves
Male Sylvari 1, 2, 3 The male version with even less texture quality
Tengu 1, 2, 3 This model has been replaced by the blue Tengu (basically a reskin of the red)
Random Mobs and creatures
Fern hound 1, 2 Alternate take on the ranger pet
Juvenile ogre 1, 2 Less rugged version of an ogre
Stalker 1, 2 Scarecrow like plant being, vaguely resembling an enemy from GW1
Kappa 1 A friendly looking fellow resembling an enemy from GW1
Goblin 1 Long arms, sharp teeth
Green drake 1 Smooth skinned drake
Underwater creatures
Blue Leviathan 1, 2, 3 The largest blue monster you'll never encounter
Brown Leviathan 1, 2, 3 The largest brown monster you'll never encounter
Manta ray 1, 2 Large gliding beast
Dragon 1 This dragon can be seen in the first trailer and on old Arah maps
Giant 1, 2, 3 Has been replaced by a much sleeker version
Boar 1 Not for consumption
Brute A 1, 2 Can be found in the 2009 Concept Art book

Note: I've tried my best to verify that these are not in game (big thanks to /u/WoodenPotatoes for helping me out behind the scenes!), but if you do know where to find them please let me know!
Update These have been identified, thanks everybody!
