Half-Life Decay: Solo Mission is a new, upcoming port of the PS2 exclusive Half-Life expansion "Decay", with the goal of rebuilding the game to work as a single player experience, thus allowing anyone to play through Decay without the need for setting up a private server, and all the headaches that come with it, all while polishing the original maps to look as good as they can without drastically changing the original artstyle.
Provided here is a Demo featuring a chapter and a half of gameplay, with four maps worth of content.
Keep up the good work bro
