A resource pack that adds three new textures from the game, for the elytra, bow, and crossbow, and a bunch of sfx. Each are pretty detailed and only work with Cit Resewn or Optfine, and when renamed :

• Elytra = High Velocity Wings
• Crossbow = Pump Charge Shotgun
• Bow = Piercer Revolver

Uppercase on the concerned letters is necessary.
I also changed the Totem texture to the gold coin (From Tzyber, credits below).
Works on all versions as long as they have the bow elytra or whatever you want from it. I’ll limit to 1.14, the crossbow’s release version.

The Elytra is V1s wings, sadly couldn’t get the 8 little wings to show like in Ultrakill, so I used an existing model with 4 wings over and the 4 others below.

The Shotgun is a model I found online (credits below), features a loading animation with the charge bar becoming from green to red.

The Piercer is a texture I found online and edited, made the cylinder on both sides, smaller, and animated, the piece I spent the most effort on. Sadly I can’t figure out how to make the left hand holding of it look normal, it’s offset.

Huge credits to :

• Vespidaze’s V1 Elytra. This is the base model I used, but slightly improved it (made the wings connect to the body and not float), link : https://www.planetminecraft.com/texture-pack/ultrakill-v1-elytra-texture/

• Deusphage’s “Marksman” Revolver datapack. I changed it to be the piercer, made the cylinder smaller, and made it spin, link : https://forums.wynncraft.com/threads/ultrakills-marksman-revolver-over-fire-bow-weapons.303851/

• Metronovich’s Pump Charge Shotgun. It’s practically unchanged, I just made it swap textures on rename, link : https://www.planetminecraft.com/texture-pack/ultrakill-shotgun/

• Tzyber for the sfx (although the bow shooting and hitting sounds are from ingame/myself) :
