Adds replayability in setup variance, adds new drones for setup and some new items that are included in every run, unlike the encounter specific mutations and relics found in packs 2 and 3. Great first add
We've had a great time with this game. It's a "bag builder" which is the first of this genre I've tried. It's been fun seeing the characters get progressively stronger each round. There's a large amount of luck in the draws from the bag, but that's part of the fun.
It also has a huge number of cards for super powers, resulting in different character builds every time.
