Hello,

The following patch adds hedgewars game. It requires sdl2-net package,

+    (description
+     "Each player controls a team of several hedgehogs.  During the course of
+the game, players take turns with one of their hedgehogs.  They then use
+whatever tools and weapons are available to attack and kill the opponents'
+hedgehogs, thereby winning the game.
+
+Hedgehogs may move around the terrain in a variety of ways, normally by
+walking and jumping but also by using particular tools such as the ``Rope'' or
+``Parachute'', to move to otherwise inaccessible areas.  Each turn is
+time-limited to ensure that players do not hold up the game with excessive
+thinking or moving.  A large variety of tools and weapons are available for
+players during the game: Grenade, Cluster Bomb, Bazooka, UFO, Homing Bee,
+Shotgun, Desert Eagle, Fire Punch, Baseball Bat, Dynamite, Mine, Rope,
+Pneumatic pick, Parachute.  Most weapons, when used, cause explosions that
+deform the terrain, removing circular chunks.
+
+The landscape is an island floating on a body of water, or a restricted cave
+with water at the bottom.  A hedgehog dies when it enters the water (either by
+falling off the island, or through a hole in the bottom of it), it is thrown
+off either side of the arena or when its health is reduced, typically from
+contact with explosions, to zero (the damage dealt to the attacked hedgehog or
+hedgehogs after a player's or CPU turn is shown only when all movement on the
+battlefield has ceased).")
