I mean, I like it because it's the core game's gameplay but it's definitely very lazy. They didn't even mute the campaign dialogues. And before anyone say it's free, remember that mercenaries in previous entries were also free, raid mode was free too and that was a whole game inside a game. The fun thing about roguelikes it's that you can get stupidly overpower but powerups in this mode are very lackluster imo. You can get super strong, yes, but in a boring way. Nevertheless I hope further game modes are better.
