01What happened

The story, straight

Mega Crit released Major Update #2 for Slay the Spire 2 on June 18, consolidating four beta patches from April 17 onward into one main-branch release. The update nerfs several Elites like Skulking Colony and Infested Prism, removes the controversial Act 3 boss Doormaker — which previously triggered a Steam review-bombing campaign — and replaces it with a new boss called Aeonglass. Mega Crit says the patch also includes a few changes that are "totally new" even for players who kept up with the fortnightly beta builds.

Mega Crit dropped Slay the Spire 2's Major Update #2 last night, folding four beta patches into one main-branch release. The big news: Doormaker, the Act 3 boss that got the game review-bombed on Steam, is gone. In its place is a new boss called Aeonglass. Several Elites like Skulking Colony and Infested Prism also got rebalanced, and Mega Crit says there are a few changes that are new even if you've been grinding the beta.

05Why it matters

The editorial take

Doormaker's removal is a direct response to community backlash serious enough to trigger a Steam review-bomb — a rare instance of a roguelike developer publicly ditching a boss because players hated it. The update also signals Mega Crit's commitment to rapid iteration, shipping a consolidated major patch less than two months into early access.

A studio actually listening to review-bomb-level backlash and removing the offending boss is uncommon in early access. The pace here is aggressive too — four beta patches consolidated into one major update in under two months. Mega Crit is clearly trying to keep the early access momentum from stalling.
