This is one of those games that's simply not worth pirating unless you're honestly treating it like a demo you might buy. The whole point of the game is party co-op, including the way the classes are designed. It's not like other ARPGs where you can be pretty satisfied doing it all solo. This is more like Helldivers meets League of Legends.

Gets stale pretty fast solo - but nice to play it coop.
