Portal 2D is modification for Counter-Strike 2D. In this mod will be only Portal gun. Only in arena maps you will have some Half-Life modified guns.
1. Unpack with WinRar. 2. Copy ct1.bmp to your CS2D/PT2D directory /gfx/player/ 3. Rename the file to mutiple it as ct2.bmp , ct3.bmp , ct4.bmp.
Thanks
a decent in game shot?
