I'm new to OMDU but I can't wait for that! The only playable mode is Survival to me, Sabotage+Endless is unplayable for lower levels.. Let's hope this will be viable to newbies too!
According to ShadeDev on the steam forums, keys will not be found in chests but discovered separately. Just wondering if anyone can confirm here as well that is something they changed recently? I don't like hoarding all my chests...
I'm hoping some of the conditions are bonuses not just curses. The examples they lay out in the videos could just make the new game mode frustrating, not fun. Part of what makes the weekly challenge work so well is these bonuses. They could do a card like "one shot kill + 10x orcs" or "10x mana, uniQue skill locked"
