Hadean Tactics is my newest roguelite deckbuilder addiction. The basic structure of the game is essentially copy-pasted right from Slay the Spire -- deckbuilding, artifacts that offer synergy, the play map, etc.

The twist here is that you also recruit and upgrade units to go along with the deckbuilding, and battles play out on tactical grid in a mostly auto-battler fashion. I say mostly, since you interact with the battle in two ways. The primary way is that every 7 seconds a turn passes, and you draw cards to play and get more energy to play them with. Otherwise, you have a small handful of orders (movement or attack) that you can give out per battle.

Including the auto-battler twist opens up even more play style variety than you usually see in this sort of game. You can play as mostly a standard deckbuilder and focus on upgrading your card draw and plays per turn. There aren't as many deck possiblities as Slay the Spire yet, but there's a satisfying variety of direct damage, ailments, summons, etc. You can also focus more on units and increase your army size. Usually, you'll do a mix of both. Most units come with abilities that will support certain deck types. Some units will occasionally give you an extra card play while others will add stacks of poison to enemies on the battlefield. This adds an extra layer of synergy to the tried-and-true cards-and-artifacts formula.

Hadean Tactics is still in early access, and there's a few pain points as a result. There are a few enemy types that are much more dangerous than others of the same tier. More importantly, the random events (which are, again, very similar to what you'd see in Slay the Spire) more often than not come with a much larger downside than upside. I'd go as far as to say that the majority of my losses were due to taking on an essentially lethal penalty from one of these events -- I've learned to just avoid paths containing events as much as possible at this point, which is a real shame.

Regardless of the issues, though, it's the most fun I've had with this formula in a long time. I'd definitely recommend checking it out if you're interested in the genre.
