We encountered few bugs, and they all occurred at the end of a level, so it just required the restarting of the server at the beginning of the next level. No command line server configuration is required, setting up and joining a server can be done through the mods UI and steam overlay. The number of enemies has been increased to account for the number of human players, adding to the level of difficulty whilst providing a great change to the original game. To install the game simply use the one click install on the Steam store. The developers have done a brilliant job. I thought this would be a buggy and hacky attempt to integrate co-operative game play into these games. Note: You do need to own Half-Life 2 to play it. Synergy tries to maintain the true Half-Life 2 game-play, while still adding in our own unique ideas. You may also install other third-party mods, such as MINERVA: Metastasis and ROCK 24, to also play them cooperatively with other players.
Synergy is the Half-Life 2 cooperative modification that enables you to play with others through Half-Life 2 and its episodes (Episode 1 and 2), as well as our own levels.
