    <h2>How to play</h2>

    <p><strong>The round.</strong> Attackers carry the spike to site A or B and plant it;

       defenders stop them, or defuse it once it is down. Plant and it runs a 45s fuse.

       First team to 13 rounds wins, and the sides swap at 12.</p>

    <p><strong>The teams.</strong> You are <span class="red">red</span> or

       <span class="blue">blue</span>; each round one team attacks and the other defends.

       Team mates carry a name tag over their head, enemies never do.</p>

       the ultimate, paid for in ult points you earn by playing.</p>

    <p><strong>On a phone</strong> the view stays top-down: the left thumb walks, the right

       thumb aims and fires, and the buttons under the map buy and cast.</p>
