Price and Buying Guide#
On Steam, The Binding of Isaac’s base game costs 48 CNY in the CN region and $14.99 in the US region (verified 2026-10-15), with a historical low of $1.49 for the base game; there is no Deluxe Edition, and the full set is the base game plus three paid DLCs, with Repentance+ free.

How Much Does The Binding of Isaac Cost Now?#
As of 2026-10-15, among the five items on sale on Steam’s US and CN regions: the base game The Binding of Isaac: Rebirth is $14.99 (US) / ¥48.00 (CN), Afterbirth is $10.99 (US) / ¥38.00 (CN), all without discount; Repentance’s US price is contradictory between two sources, and this page does not pick a winner; Repentance+ is a free DLC.
| Item | Steam App ID | US price | CN price | Notes |
|---|---|---|---|---|
| Base game, The Binding of Isaac: Rebirth | App 250900 | $14.99 | ¥48.00 | No discount; checked directly on the official store API for both regions |
| Afterbirth | App 401920 | $10.99 | ¥38.00 | No discount; checked in both regions and cross-checked with a price tracker |
| Afterbirth+ | App 570660 | $10.99 | Not verified | US figure is a single-source snapshot; the CN API returned no price data |
| Repentance | App 1426300 | $10.99 or $14.99 | Not verified | Contradictory sources: store-page snapshot $10.99, tracker bundle page $14.99 (updated 2026-10-12); live store price prevails |
| Repentance+ | App 3353470 | Free | Free | Free DLC; activation requires all three paid DLCs |
Why Does Repentance Have Two Prices?#
On the verification day, the dependency-list snapshot on the Steam store page showed Repentance at $10.99, while the price tracker SteamDB’s package page (SubID 500840) showed $14.99 — both records from October 2026. The tracker’s price basis was found during this verification to possibly include a bundle price (its historical-low section has the same issue), so neither figure can be confirmed as the standalone current price. This page lists both numbers instead of choosing for you: before ordering, open Repentance’s product page on the Steam store and glance at the price tag — that glance beats any snapshot. The same applies to Afterbirth+’s CN price — the API returned no data, so this page will not guess.
What Are the Historical Lows? Wait for a Sale or Buy Now?#
Conclusion first: this is a game with massive discounts — during the summer sale in late June 2026, the base game was cut straight to one-tenth of its price, yours for $1.49; if you are not in a hurry, waiting for the next major sale is the cheapest way to buy.
| Item | US historical low | Discount | Timing | Confidence |
|---|---|---|---|---|
| Base game | $1.49 | -90% | Late June to early July 2026 sale period | Cross-checked by two independent sources; reliable |
| Afterbirth | $1.09 | -90% | 2026-06-25 (summer sale) | Tracker record; reliable |
| Afterbirth+ | $3.57 | -90% | 2026-06-25 | Tracker figure may be a bundle price; for reference only |
| Repentance | $5.06 | -90% | 2026-06-25 | Same as above; for reference only |
The base game plus Afterbirth had a combined historical low of $2.58 — during a big sale, the game’s core experience costs about the price of a milk tea. The Afterbirth+ and Repentance historical lows are not summed because their price basis is in doubt, but all four items show -90%-tier discount records on the same day (2026-06-25), so a sitewide one-tenth-price sale during major promotions is a documented level of discounting.
Three Criteria for Deciding Whether to Wait for a Discount#
- Full price, not in a hurry: wishlist all five items and wait for a major sale. The historical lows come from the June 2026 summer sale; nobody can guarantee the same depth will repeat, but for this game, waiting for a sale is a historically proven way to save.
- Full price, want to play now: buy the base game directly, ¥48.00 in the CN region. This is a game built on replayability — by the volume of this site’s guides (700+ items, 34 characters, 100+ Bosses), 48 CNY spread over playtime is almost negligible.
- Hoping for a freebie: don’t wait. The game has never been on Xbox Game Pass (verified twice, November 2023 and August 2026, both negative), and its PlayStation Plus free-games record stops at November 2014 — “waiting for it to go free” is not a realistic way to save.
Is There a Deluxe or Gold Edition? The Edition Structure Is Simple#
No. The game has no Deluxe Edition, Gold Edition, Yearly Edition, or Season Pass; all content is a single line: the base game plus four DLCs — Afterbirth, Afterbirth+, Repentance, and Repentance+, with Repentance+ free.
| Item | Release date | Positioning |
|---|---|---|
| Base game, The Binding of Isaac: Rebirth | 2014-11-04 | The complete starting point of the game, independent of any DLC |
| Afterbirth | 2015-10-30 | First paid DLC |
| Afterbirth+ | 2017-01-03 | Second paid DLC |
| Repentance | 2021-03-31 (Steam PC first); consoles 2021-11-04 | Officially positioned as the “final DLC”, containing remade content from the community mod Antibirth |
| Repentance+ | 2024-11-18 | Free, released for Rebirth’s tenth anniversary, adding online co-op |
Two points worth factoring into the purchase decision:
- Repentance+ is free with a condition: the download costs nothing, but activation requires the base game plus all three paid DLCs — Afterbirth, Afterbirth+, and Repentance. In other words, the cost of “buying the whole family” stops at three paid DLCs; the fourth is a bonus — provided you actually buy them all.
- Official support continues: as of verification, the latest major update is 1.9.7.13 (released 2025-09-10). Buying in now means buying a living game that is still updated, not a swan song.
Bundle or Buy Separately — Which Is Cheaper?#
Per the 2026-10-15 snapshot, the official bundle has almost no price advantage; it is worth comparing prices on the spot before ordering.
The “Rebirth Complete Bundle” includes the base game plus three paid DLCs at a snapshot price of $50.96. Buying separately at the current prices in the table above: base $14.99, Afterbirth $10.99, Afterbirth+ $10.99 — three items total $36.97 — plus Repentance: if it is really $14.99, buying separately totals $51.96 and the bundle saves $1.00; if it is really $10.99, buying separately costs only $47.96, $3.00 cheaper than the bundle. Precisely because Repentance’s current price is itself in doubt, there is no “always pick this side” answer here: check Repentance’s standalone price, do the math, and pick whichever side is cheaper.
CN-region players reason the same way: base ¥48.00 plus Afterbirth ¥38.00 totals ¥86.00; the CN prices of Afterbirth+ and Repentance were not verified this time, so just compare “buy separately” versus “bundle” in the cart at checkout. The price tracker also shows Nicalis multi-packs of its own games (e.g., Blue King Collection) for players who want to collect the publisher’s other titles; Isaac-only buyers can ignore them.
How Should New Players Buy? Conclusions by Scenario#
| Your situation | Suggested purchase |
|---|---|
| Never played, unsure if you’ll like it | Buy the base game only (¥48.00 CN / $14.99 US). The base game is a complete game; use it to test your taste first |
| Played the base game, sure you want to go deeper | Add Repentance — the officially positioned “final DLC” with the largest content volume; see Repentance DLC New Content Guide for what it adds |
| Want online co-op with friends | Base game plus all three paid DLCs, none skippable, and Steam version only; rules in Local Co-op |
| Very low budget, not in a hurry | Wishlist everything and wait for a big sale — in the 2026 summer sale the base game was $1.49 and all DLCs were at one-tenth price |
| Switch 2 players | Wait for the Repentance + Online physical edition on 2026-11-19, $69.99 — the cartridge holds full data, not a Game Key Card |
| Mobile players | The iOS version launched in 2017; the current App Store price was not verified this time — go by the store page |
Three supplementary criteria:
- The base game is the only must-buy: all DLCs stack on top of it; no content requires skipping the base game and buying DLCs first.
- Don’t buy half the set for online co-op: Repentance+ requires all three paid DLCs to activate — base game plus Repentance alone cannot start an online match, whichever piece is missing.
- Online co-op is still a Beta: officially flagged as possibly unstable and even save-corrupting; fortunately the game keeps save backups from before Repentance+ was enabled. After buying, read Local Co-op for the rules, and troubleshoot issues via Crash and Black Screen Fixes.
Has It Been Free on Subscription Services?#
Once, and that was twelve years ago: in November 2014, the game launched on PlayStation Plus free games (both PS4 and PS Vita) the same day the base game released, after being teased in advance by a publisher producer that September. Beyond that, Xbox Game Pass has never included the game (verified twice, November 2023 and August 2026, both negative), and other free channels like Epic giveaways have no public records either.
The implication for the buying decision is direct: the “wait for a freebie” path does not exist for Xbox players, and for PlayStation players it hasn’t happened in twelve years. Treat it as an option that will not happen, and budget by current prices and discounts.
Beyond Steam: Platform Differences at a Glance#
| Platform / Channel | Situation | Notes |
|---|---|---|
| Steam | The most full-featured version; Repentance+ online co-op is currently Steam-only | The only path to online matches, up to 4 players |
| Epic | Has a Repentance bundle including all DLC through Repentance; can be played offline after install | No Daily Run; whether online multiplayer is included is unconfirmed |
| GOG | DRM-free version | Official forums note some online features are missing (such as the Daily Run) |
| PlayStation / Xbox | Repentance console version launched 2021-11-04 | Console store prices not verified this time — go by the store page |
| Nintendo Switch 2 | Repentance + Online set for 2026-11-19, physical edition $69.99 | Cartridge holds full data, not a Game Key Card; whether cross-platform multiplayer will be supported after launch is officially unclear |
| iOS | Launched 2017 | App Store price not verified |
There is no need to worry about specs at all: this is a 2014 2D pixel game whose official minimum requirement is only 449 MB of storage — old machines run it fine; see PC Requirements. For online play, remember one thing — online features are currently fully provided only on the Steam version, officially noted as missing on GOG, and unconfirmed on Epic; if you buy for online, buy the Steam version.

One last honest sentence: for its content volume at this price, 48 CNY at full price is already generous, and the $1.49 historical low is nearly free. The only wrong way to buy is to keep not buying while waiting for a free-games rotation that hasn’t happened in twelve years.
