+      about rich, colorful, arcade-like atmospheres? How about retro
+      Sci-Fi? Then you're going to love what Alien Arena has in store
+      for you! This game combines some of the very best aspects of
+      such games as Quake III and Unreal Tournament and wraps them up
+      with a retro alien theme, while adding tons of original ideas to
+      make the game quite unique.
