I managed to connect, played for 5 minutes. Why did not I get to take anything but a knife (((I met only 2 opponents and every time I died)) Well, it pleases at least that there really is a game in whatever state it was
You have to choose the gun before entering the game, just to have it as an option in a game. Make sure, that the text below the gun says "OWNED" before you enter the play room. In that case, with the help of numbers of your keyboard, you will be able to switch the knife to guns.
