Defect is part of the launch roster, but Mega Crit has not yet given the class a dedicated reveal article. The useful first question is what is confirmed and how carefully you should approach Defect in week one.
Defect is back in Slay the Spire 2, but official public detail is lighter than it is for Silent, Necrobinder, or Regent. So the best week-one approach is a careful 'what is confirmed so far' guide, not an overconfident tier list.
For readers returning from the first game, the main warning is simple: do not assume every old line, orb expectation, or autopilot build survived intact just because the class name did.
Verification note
Built from official roster confirmations and launch-era gameplay material. Exact class systems need more live-build documentation.
What to focus on with Defect
This guide is built to answer three things fast: what is confirmed about Defect, what makes the class feel different, and what matters in the first few runs.
Think of it as a first-pass class read before you move into build ideas, mechanic explainers, or deeper matchup talk.
Start here before you jump into build speculation or tier lists.
Open the linked mechanics pages if Defect depends on a signature keyword or resource system.
Treat this as an early access primer, not a final meta verdict.
Mega Crit's release-date post confirms Defect as part of the five-character launch roster. Beyond that, the public detail is mostly broad gameplay material rather than a full mechanic article.
That is enough for a launch roster page, but not enough to pretend the live class is already solved.
Approach Defect as a returning shell in a changed environment. The sequel adds new universal systems like Enchantments, Quest Cards, Afflictions, and Alternate Acts, so even a familiar class ends up making different choices.
The safest advice is to stay flexible, keep the deck clean, and not commit too early to old archetype labels until the early-access card pool settles.
Defect is a page to revisit quickly once better live data exists. For now, honesty is stronger than pretending you know more than the official reveal trail actually provides.
Comparison
Defect returns, but the public reveal trail around the class is much thinner than it is for Silent, Necrobinder, or Regent. That alone changes how confident players should be at launch.
Slay the Spire 1
Defect was a class many veterans could play from memory because the orb shell felt so distinctive.
Slay the Spire 2
Defect still gives returning players that instant recognition value.
Why it matters
The class is still a bridge point for veterans, even with less public detail.
Slay the Spire 1
The first game eventually produced very stable old habits around Defect's familiar shell.
Slay the Spire 2
The sequel gives you the class name without an equally detailed official class article, which means caution has to replace certainty.
Why it matters
A familiar name with limited reveal data is exactly how players over-import old assumptions.
Slay the Spire 1
Veterans often entered Defect runs with strong old archetype expectations already in mind.
Slay the Spire 2
Keep the deck cleaner and stay more flexible until the live card pool teaches you which old instincts still hold.
Why it matters
Launch-week Defect rewards humility more than nostalgia.

FAQ
Yes. Defect is listed in Mega Crit's five-character launch roster.
Not in the same public Neowsletter format that Mega Crit used for Sly, Doom, Stars, or Forge.
No. Even if some class themes remain familiar, the sequel's new systems and changed card pools mean old autopilot assumptions are risky.
