Can i meet other players in this game

When i was entering game it sad that this is singleplayer and that there only ai??

The game gives you this answer very clearly, literally within a minute of playing. Have you even played it?

Yes, the players you see running around killing the monsters in the game are bots, not real players. You can chat to real players if you are in a guild though. However due to bugs in the game i can’t join a guild...
