Heya, welcome
Hellgateaus has been a community dedicated to the SP portion of the game, producing various mods for it over the years, including the Revival series.
If you're looking for an online server, look no further than the
London 2038 project Do note, it's currently in a closed phase, but will be transitioning to an open phase after this final wave.
Activity currently flactuates massively; there are more than 1000 tester accounts, but many testers have been active since the beginning of the year, so many may be idle depending on the waves and the bugfixes they coincide with.
The project's
Discord server and
facebook group should be very informative on that front.
As for the game's handling of deaths, SP provides players who die in combat zones with 2 options; either restart at the last station (and possibly use a PRD item to return to the zone, if it was set up beforehand), or revive as a ghost in the zone, look for their headstone (placed where they died), and revive with half health once they approach it.
2038's MP version also offers a Hardcore mode, however, where death is permanent. Not unlike Diablo
