This looks awesome, the procedurally generated dungeons are a great addition.
I can't wait to get my ass handed too me by this game!

so i'm still unclear. the dungeons are procedurally generated but locked so that the entire community is playing the same map for a while and then changed after a certain time period?

Okay, for a hack-and-slash kind of game this looks like it could be fun.

No, the upper city is where the main game and story take place and that's not procedurally generated. There is another section below the city that's procedurally generated and each player effects the way it's generated. If you leave and then return later, the dungeon will be different.

Any idea what this is actually for though? I mean, is it just a time sink? Something to do because your bored? Or is there a point to this dungeon crawling?

There ARE rewards down there so I amagine rare healing potions or rings and perhaps a weapon or two.

Thats pretty cool actually. Im really ready for this game. Might be my most anticipated game right now actually

Sounds like it was somewhat adapted from the path of exile map system...which is awesome!

This game looks sweet. I'm sure it won't disappoint.
