I need someone for Hail to the King. And there are only two arenas left where you'd have to fail for me.
I only have access to the game until friday, but until then I can help you too if you need some of the online stuff.
Currently searching for people to boost the online achievements of:
Moon Diver, Resident Evil 6 Three Mode DLC, Assassins Creed Revelations 4 Player DLC Achievements
This list is always up to date.
