    When the round is running, the ticket overview is shown in the header. Your objective
    is to defend your team's tickets and withdraw the tickets from the opposing team as
    quickly as possible.

    There are two ways to withdraw the tickets from the opposing team. First, by killing
    the player and second, by taking the spots. A spot withdraw 0.05 tickets per second
    from the opposing team.

    The battlefield has two special features: First, there is a point of interest in the
    north and south. And second, there are loot boxes scattered throughout the battlefield.

    PvP battles and the conquest of the spots are the deciding factor to win the round.

    The battlefield is created when at least two players are online.

    There is no biter evolution from pollution, time or destruction.]]
