The developers wrote about this in their blog.
Previously, the game was already shown to the public, but only in the business zone. This time everyone who comes to the exhibition will be able to play the game.
In this demo, as last time, players will be able to choose one of three ready-made characters. But, unlike last year’s demo, here the characters will already be with 10 years of experience. Thus, the players will be in the middle of the game company. This will give players the opportunity to participate in epic battles of huge armies and sieges of fortresses.
You can also try the multiplayer part of the game. In particular, captain modes and team PvP.
