+      Tremulous is a free, open source game that blends a team based FPS with
+      elements of an RTS. Players can choose from 2 unique races, aliens and
+      humans. Players on both teams are able to build working structures
+      in-game like an RTS. These structures provide many functions, the most
+      important being spawning. The designated builders must ensure there are
+      spawn structures or other players will not be able to rejoin the game
+      after death. Other structures provide automated base defense (to some
+      degree), healing functions and much more...
