Knight: A knight that has been in the game's resources since 2004; it had its own unique skeleton, which made it incompatible with animations from the standard knight (there is also a reference to it in the form of the perk "Fallen Knight"). psatkha claims that this is a banned Godrick, but who knows.
Marksman: A crossbowman with a helmet from the alpha version (without horns) and a texture in the style of the beta version.
Sniper: My alternative version of the archer upgrade (not as overpowered as the archers, but not as useless as the crossbowman).
Archangel: An archangel with a sword from the alpha version.
And I made some minor adjustments to the models that were present before the update.
