Is IsaacModExtend available on PC?

When was the mod last updated?
The source listing reports April 12, 2025 as the last file update. A later comment or catalogue refresh does not mean the mod file changed. Official source ↗
What does the ModOrNot Score mean on this page?
It is a 0–100 momentum signal: 50% subscriber-growth velocity relative to mods in the same game, 20% favorite growth, 20% view growth, and 10% update recency. It is not a quality rating. The current score is 30.3.
Are these the real Steam Workshop numbers?
ModOrNot stores public Steam Workshop counts from its collection runs. The totals shown here are the latest counts stored in our catalogue; changes over time are calculated from recorded observations, not invented values. They can differ from the live listing until the next collection.
How is the rank computed?
ModOrNot compares tracked active Slay the Spire mods by their current stored subscriber totals. Rank #1 has the most subscribers; equal totals share a rank. The rank is calculated when this page loads and can change as counts or the catalogue change.
