I recently picked up a bunch of free sounds from a professional sound developer's website, and thought that they would sound pretty cool if I put them in Sauerbraten.
So I edited a lot, adjusted them here and there, and tried them out. In my opinion, they sounded great (but that's just my take on things). So here they are, replacements for all weapon sounds, all item sounds (e.g. pickup), weaponswitch, explosions, jumppad, and teleport. Enjoy (but be sure to tell me what you think of them)!
