Is the co-op in this similar to how Gauntlet was?
Do you mean couch-co-op? 2 or more guys at the same machine? No....everybody need his own PC for Grim Dawn.
Co-op is means that you can play together in a local area network (LAN) without an online-connection.
If you want to play couch-co-op you can play Vctor Vran or Vikings-Wolves of Midgard for example.
I have 2 machines set up for when friends come over. It's sad that there is no local co-op as thats the most effiecient when playing with friends.
I can play it online with other computer in same house. Was just wondering how the gameplay style for co-op is like? Wondering if its like 1980's Gauntlet game or has a different play style?
