DW is still active mostly in European regions. We play DW several times in week but we try to organize bigger sessions in Fridays and/or Saturdays.
Here are links to Discord channels:
DWLD - mostly for european time zones players (but not only eu)
FPSchazly - mostly for american time zones players.
DWLD is mainly for DW game, FPSchazly - DW is NOT main game there. Also DWLD have almost everyday activity.
I know that Russian language players have own community but they probably meets via VK (russian "facebook") or Tunngle and now i haven't good contact with them.
BTW Co-op is boring - better is Team deatchmatch mode where side fights against opposite side. Missions often have background, fabula, and task.
We play with RA 1.43 mod via Directplay connection. I hope you will join us soon.
My nick is Pepe and i am from polish community.
