The Steam Summer Sale has delivered a lot of deals this year, but this one is hard to ignore. The Binding of Isaac: Rebirth Complete Bundle, which normally sits at $50.96, is currently 90% off, bringing the entire package down to $5.09.
That bundle includes Rebirth, the Afterbirth expansion, Afterbirth+, and Repentance, plus the free Repentance+ update that dropped later. Every piece of content Edmund McMillen and his team have released for this game, for about the price of a coffee.

A deal that blows every previous Isaac sale out of the water
Here's the thing: Isaac goes on sale fairly regularly. But this discount is genuinely unprecedented for the bundle. The previous lowest price the complete package had ever hit was $26.46, and that was a limited window. Before that, the bundle rarely dipped below $35. Getting it for $5.09 puts this in a completely different tier of value.
To put the hours-per-dollar math in perspective, Rebirth alone has players regularly logging 200 to 500 hours before they see most of what the game has to offer. The Repentance expansion added so much content, including new characters, items, floors, and a reworked final chapter, that veterans treated it like a full sequel. Paying $5 for all of that is a harder argument to dismiss than almost any other deal in this year's sale.
Why Isaac still holds up 15 years in
McMillen originally built The Binding of Isaac as a side project, a quick experiment to understand roguelike design before moving on to what he considered his real work. That game became Mewgenics, which launched earlier this year to strong reception. But Isaac took on a life of its own. Fifteen years after the original Flash game, Rebirth and its expansions are still regularly cited as the benchmark for the genre.
The key here is the item synergy system. With over 700 items in the Repentance build, the combinations are effectively endless. Two players can run the same seed and come out with completely different experiences based on what they prioritize and what the floor layouts hand them. That replayability is why the game still has an active player base and why a 500-hour save file is not unusual at all.
McMillen's legacy and what comes next
With Mewgenics now out, McMillen has officially delivered the project Isaac was always meant to precede. The cat-breeding strategy roguelike has been in development for over eight years and launched to an enthusiastic reception from fans of his earlier work. For anyone who wants to understand what makes Mewgenics click, going back to Isaac first is a reasonable starting point, and at $5 there is no better time to do it.
The Steam Summer Sale runs for a limited window, so the $5.09 price will not last. If you have been sitting on Isaac for years or want to fill out your DLC collection, this is the moment.
