Ballmen is a total-conversion for Half-Life 2 featuring frenetic, fast-paced deathmatch with a unique twist: wallwalking. Essentially, any surface is traversable, including walls and ceilings. Combine that with eight weapons and a host of power-ups, and you get Ballmen. The mod is currently in beta stages. Visit our website for more information. Beta 1.5 now available for download.
