You play as one of the human rebels - Frank Harrison, who's currently in his hideout outside City 17. He's woken up by the Citadel explosion, caused by Dr. Freeman and Alyx Vance at the end of Half-Life 2. The evacuation of the City 17 is in progress and he has to leave his house to fight his way back to City 17 to join an evacuation train while there's still some time. Gather your supplies and an old HEV suit and explore the territories of the City 17. Play your role in the events, that took place during the original Half-Life 2: Episodes 1 and 2.
Only recently I've found out that DangerousWorld is Synergy positive and now you can enjoy the co-op support so anyone who would like to play this mod with his/her buddies, you are all set.

Only recently I've found out that DangerousWorld is Synergy positive and now you can enjoy the co-op support so anyone who would like to play this mod with his/her buddies, you are all set. I'm really happy that my mod has been granted this support even though I didn't know about it until this moment. I haven't tried it out yet so let me know how it performs.
As far as DangerousWorld 2 is concerned, I desperately lack free time as I'm going through the very last semester before my Bachelor's thesis and I'm overloaded with work. I sincerely hope I will find more time for it sooner than later.
I also want to remind you that the download of the full version of DW version 2.0 is missing a map. dw_ep1_04 has to be uploaded anew as it keeps freezing during installation, I need to give it a one more go. So if anyone wants to play, please, download also this missing map. I apologize for the inconvenience.
Cool. Does it work in Obsidian Conflict too?
wat he said.
I'm not sure at this point.
Sofar the only multiplayer modification we have looked into was Synergy.
Thank you for reming me thou, I will add it to my ToDo list for the weekend.
Yay new coop stuff !
