The knife, bayonet, machine gun, Unmaker and Dark Claw. Anything else you see in the design doc was not seriously considered; they were weapons that would have made it in if there was enough time and the balance would work out.
It currently replaces the Blur Sphere, as I don't find partial invisibility very useful. The first person sprite is a 'new' sprite created from the Doom 3 hell knight's hand. The sprite are not final, as I feel that the first person sprite suffers from the palette limitations. I feel that making it less 'shiny' will circumvent the issue it is currently having. It's behavior is also not final, currently it only fires a few projectiles in a large spread.
Another thing I'd like to show off are some score items.
Currently I'm conflicted on their inclusion, as all these strange, arcane artifacts appearing so often together are strange. I'm considering either removing them entirely, or creating some UAC-themed score items that appear in UAC environments to tackle this issue. Let me know what you think about the Dark Claw and the score items!
