I'd like to see it. Hexen Coop is a "same story, different day" kind of deal, but survival would encourage actual teamwork and item sharing. Not to mention it'd be a blast. Although I forget if Discs of Repulsion affect teammates (this could very well lead to teamkills in areas with pits or squishing traps). But otherwise the only hurdle I see is what you stated above, how inventory would be handled.

Is it possible with a mod?

Discs affect team mates, as they don't have DONTBLAST on them. You can apply it easily with additional mods though.

I'm up for this idea, sounds really great! Hexen is one of my favorite games of all time, so seeing some survival support would be awesome.

i wouldnt mind survival support for hexen (and by extension, anything that uses hubs in general) as coop lacks any kind of penalty or challenge, even if enabling the cvars to lose stuff on death, as u can just keep going and eventually win anyways, itll just take a wee bit longer

this could be of some interest, however some of the wads in the op are outdated, but any newer versions can be found by searching for hexcoop here: http://www.[bad site]/wads

I agree that this is what should happen. Unfortunately, the current map reset mechanism can't do that. It is designed (and hardcoded) to reset the map to the state when it was first loaded. To achieve what you'd like, the best option would be to ditch the current system and to create a new one based on loading saved game states, which IIRC ZDoom is already doing when you re-enter a map on a hub.
