If you wanted FreeDoom weapons for me to smoothen animations out of them, you may download it. Better than Perkristian's smooth weapons.
1. Extract the file to your FreeDoom directory (if you have the original Doom 1 and 2 iwads, it's not right) and make sure you have: freedoom1.wad and freedoom2.wad
2. Drag rzanims.wad to zdoom.exe
The Angle Grinder and the Skag 1337 are not listed due to a problem with FreeDoom animations. So just deal with these 6 weapons with the smoothened fist.
