This looks interesting, can't wait to see the next version of this. I used to play this quite extensively some years ago, one of the few mods that actually have a working molotov cocktail in it.
Is that remaining in the mod still?
Of course! It's one of the 4 grenade types. (Frag grenade, gas grenade, cluster bomb, and molotov cocktail.)
You can actually download the latest alpha if you wanna try it out. http://zandronum.com/forum/showthread.php?tid=272
You'll need Zandronum, skulltag_actors.pk3, skulltag_data.pk3, and sst_v1.4rc3.pk3 though. Sorry about all the files, I just figured it would be easier to keep filesize to a minimum if I only include what's 100% necessary for Mercenaries and just include the rest via DECORATE inheritance.
