When playing in Battle, you can have 2 players connected via LAN or Steam to play, or on the same computer, before searching for a match. Everyone chooses their Awesomenauts in the standard way, and the game begins when the host starts the game or the timer reaches 0 seconds. If there are open spaces filled by bots when you begin the match, a random person online can join from the Quick Match option. To prevent this, you would have to start a Private Match. In this mode, maps are selected randomly.
