Slay the Spire 2's monsters invade every act, and the ? rooms turn into Anomaly Company corridors.
Slay the Spire 2's monsters and bosses invade all three acts of Slay the Spire, and some ? rooms become Anomaly Company stops.
Slay the Spire 2 in the Spire. 44 StS2 monsters across 33 fights: Overgrowth in Exordium, the Hive in The City and Glory in The Beyond, including the Ceremonial Beast, The Insatiable and the Queen as bosses. They keep their StS2 moves, move patterns and powers (Territorial, Plow, Sandpit, Hex, Chains of Binding...) and their StS2 status cards. About half of every fight pool is StS2.
Anomaly Company in the ? rooms. Anomaly Company's real office and hotel posters, notes and signs: memorise it, walk the corridor again, and call it: stable, or anomaly? A right call earns a relic; a wrong one costs HP and the timeline resets once.
Your games, not copies. You need Slay the Spire. The mod reads Slay the Spire 2 and Anomaly Company from your own Steam installs on first start (art, names, text); nothing from either game is in the download. Missing one? The main menu tells you and only that part is off.
Not in this version: animated StS2 monsters (they use their first idle frame), Anomaly Company's sounds, card overlays for StS2 afflictions.
