Slay the Spire 2
The sequel to the deck-building roguelike game Slay the Spire. It features imperfect information and randomness, and its large action space poses challenges for neural network learning.
Timeline (last 90 days)
A Reddit user launched a project called OstyAI, with the goal of building a "superhuman" AI coach for Slay the Spire 2.
Slay the Spire 2 is a deck-building roguelike game.
The action space of Slay the Spire 2 is extremely large; each turn the player must choose which cards to play, whether to use potions, or to end the turn.
OstyAI is positioned as a "superhuman STS2 teacher," emphasizing that the AI can explain its decisions to help human players improve.
In games like Slay the Spire 2, MCTS faces two major challenges: random events make the tree's branching factor extremely large, and a single simulation requires fully simulating an entire combat, making computation costly.
Some researchers pointed out that the randomness of STS2 makes reward signals sparse, and training difficulty is far higher than in deterministic games, possibly requiring imitation learning or curriculum learning to accelerate convergence.
In Slay the Spire 2, a single run may last hundreds of decision steps, while the win/loss signal appears only at the end.
