I launched the multiplayer exe file then I hosted the game but it starts the standard game VS bot. When my friend is trying to join me he also instantly join the game VS bot.

I couldn't find any info how to properly start multiplayer game. There is no list or anything. After one guy is hosting and second one is typing IP it's automatically starts the game VS bots.

In short:
I host the game, and I play VS bot.
He joins the game via hamachi IP but he also does play VS bot so I doubt we are on the same server.

Other games via hamachi works with my friend including dosbox emulated games with IPX.

Any help? What do we need to click after we are in the game to connect us each other?
