THIS PROJECT IS NO LONGER BEING WORKED ON Sven Co-op recent steam release got rid of most the weird additions and stitches maps together for far less loading screens making this project no longer necessary or worth it. Demo downloads will stay up for the research of other modders and the player models included. Thanks everyone. Unity is a Cooperation mod for Half-Life that aims to keep the campaign as vanilla as possible, While still being co-op. That means no monsters that weren't in the original game and no new weapons. Just good old Half-Life the way it was meant to be played but with your friends.
