Adrenaline Gamer is a full Half-Life Deathmatch replacement mod and is considered to be the OSP mod for Half-Life. For those of you who are unfamiliar with Adrenaline Gamer, think of it as an extension to HLDM which offers more choices, more control, more options, more features... and ultimately more fun!
