We are getting ready to open a new server with a unique game mode - Defense. In this mode, monsters attack the players in waves, and the players have to destroy them. The difficulty increases with each wave. There are bosses too.

Everyone is invited to the closed (semi-closed) beta test of the new server.
The test will take place tomorrow (November 15, 2015) at 19:00 Moscow time. To take part, say so in the comments and include your nickname and SteamID. I will send you the server password in a private message. Server address: 78.155.209.111:27040
