+  <description>
+    <p>AssaultCube is a free, multiplayer, first-person shooter game, based on the CUBE engine.</p>
+    <p>Taking place in realistic environments, with fast, arcade gameplay, it's addictive and fun!</p>
+    <p>With efficient bandwidth usage, it's low-latency and can even run over a 56 Kbps connection. 
+      It's tiny too and on the correct settings, it can even run on old hardware (Pentium III and above).</p>
