Speaking of multiplayer, the item linked in the first post only works in single-player mode, though, I made some changes to my local copy to make it multiplayer-compatible (I think), I'm not certain if it actually works properly or not as I'm incapable of doing the test.
To think of it, most if not all of my ACS-based item submissions aren't multiplayer-compatible. I'm gonna need to update them if I can.
Heh, well I'm sure it's intended for Heretic or Hexen.
Yes, the amulet is actually meant for those games, but as I said in my last post I was thinking of making one for Doom as well. I even put a sprite together for it.
As for "the item doesn't make sense in Doom" thing, I tend to agree. I could've used the "since when Doom ever made sense" argument, but then again, I don't think it really applies in this case, to be honest, even for Doom.
Nevertheless, if you really want to I can post a submission for it, since I don't have any problem with it at all.
