Hot diggity dog! The Cauldron people (person really) are at it again! There's new Cauldron content incoming any day now. I've played most of the five heroes, six villains and five environments in Tabletop Simulator and everything I've seen is great. The villains run the gamut from challenging to utterly savage with some pretty cool mechanics, the heroes are fun and varied with some pretty unique mechanics of their own (Pyre 'irradiates' cards in players' hands for a variety of effects and Drift has a track that you slide a token up and down to control how her cards act) and the environments are some of the most fun and interactive-without-being-invasive (some of the old Cauldron environments were of the oh-shit-the-villain-isn't-the-problem-anymore variety, though there are 2nd edition versions of three of those available now too) ones yet.
I'm super hyped for more Sentinels! Especially some standard format villains which we haven't seen a new one of for a long time now.
There's a huge thread over on Board Game Geek with all the details.
In the interest of full disclosure, I'm not affiliated with Cauldron at all, but I do keep a close watch on the development, and right now tosx (the creator) is waiting for approval from GtG to release Adrift on Drive Thru Cards (I understand 50% of the proceeds go to GtG) and I was kind of hoping this post might speed things along if it got noticed. So, if you're interested in some fantastic new content, make some hype!
Between this and Sentinels of Earth Prime on the horizon, it's a fantastic time to be a Sentinels fan!
