Half-Life 2 Monster_Mash Singleplayer Map

If you can do this then you will be rewarded with your life! How generous am I? :) Otherwise you will be slapped to death. Muhahahaha.
This map is a Half-Life 2 Single Player fun map, the main goal is to stay alive and to do this you need to conserve your ammo and not use the strongest weapon on the weakest target, and vice versa.
