Re: Dead Space 3 (PC) Failed To Join Game Error
The easiest way to play co-op again is Hamachi!
1. create a network where both of you are inside!
2. start Dead Space 3
3. host starts a private game normally
4. your friend (or you, as the case may be) joins the game normally via "join friends" (you see him through Hamachi now again immediately)
5. have fun and coop game!
Addition:
I was able to exit Hamachi again after successfully connecting (was in my host's lobby) and everything ran normally through EA! Apparently you need Hamachi only to find each other!
Hope it helps! 🙂
