Overall, this is a straightforward simple add-on that adds a few new game mechanics. The addition of scars, boons, new campaign cards and campaign mechanics change the variety on how day 1-3 encounters work and allows multiple games to be strings together via a campaign where players take their characters from one game to the next. This all works really well within the existing base game and ruleset, and from my initial playthroughs so far, adds quite a bit of flexibility and additional tactics to consider for progression.In the box are (25) Boon/Scar cards, (21) Day 1-3 Encounter Cards (which is great for even adding more variety to the base game without having to play the Age of Tyranny ruleset), (10) Campaign cards, (7) Epilogue cards, (20) Scar tokens inside a nice clear dice case, a neoprene snapshot mat to save progress if taking a break between campaigns (basically place everything on it to snapshot and take a picture), and a reference sheet for the rules. All of the parts within this add-on are high quality and water resistant. The card stock itself feels good to hold and is PVC to help it withstand lots of use and the occasional wet surface.The best thing about this expansion for me is the added campaign cards and snapshot mat. The base game's replay ability really benefits from some additional variety there. And the snapshot mat is just incredibly useful when playing the game for short intervals instead of fully through. The scar and boon system is also an interesting addition that adds additional challenge as you progress through multiple runs, carrying over skills from previous games but also scarred from battle or training fatigue. A scar token essentially takes up a skill slot on your character's sheet, preventing that stat from being increased or enabled. The nice thing about the scar system, is that it challenges players to think of different approaches and explore skill trees they have not considered before. When battles are lost, boon cards can be drawn which have an opportunity to remove scars. This is my only complaint about this system as the consequences for losing are somewhat more rewarding than they should be, which could incentivize losing on purpose just to pull a boon. This might be a part where some additional house rules could help prevent that scenario.All in all, I really enjoyed playing this expansion. It is a small kit, and I think the box could have been a little smaller to hold everything, but it does bring a few much-needed additions to the base game. Some of which, in particular the campaign cards, would have been nice to see by default in the base game. But it is good to see them here as an add-on as well. The price does initially seem a little on the high end for what is included here, but with the materials in mind, being below $35 is reasonable as Chip Theory Games produces very high-quality parts that will last many gaming sessions.I have included a few photos I took while playing through a campaign. I have noted on those photos where components of the base game are also mixed in. The game itself is officially rated for ages 12 and up but may be higher in practice for full enjoyment. Once the basics are learned from the base game and this expansion however, it is very intuitive and easy to play. The included instruction sheets do a great job referencing the rules.
