The paradox of Isaac

Binding of isaac afterbirth plus is the second expansion of The Binding of Isaac: Rebirth, which comes out just over a year after the premiere, Afterbirth, and more than two years after the base game.


On paper, the new contents, which go alongside those already existing, are not bad at all : more than fifty-five new objects; a new final chapter; a new playable character; a new mode; the introduction of daily challenges;


five new classic challenges; new Steam goals; new bosses, including one for the new final; new enemies; a hundred new rooms; last but not least, openness to modders with tools and integration with the Steam Workshop. In short, it really seems a work worthy of note and that is worth the asking price …

We played Afterbirth +, the new expansion of The Binding of Isaac: find out if it’s worth what it costs


Let’s ask ourselves a very simple question: are the new contents valid? Reviewing Afterbirth we affirmed that by now The Binding of Isaac is a brand and that the anarchic spirit that had generated it was fading in the awareness of having a very salable product.


Binding of isaac afterbirthshows exactly where the game is leading the philosophy, that is to an accumulation of additional content quite useless and designed just to spend more money to passionate players , content that does not add almost nothing to the game experience, but only lengthens it in an artificial way.

The paradox of Isaac
One of the new bosses: he recycles the ideas of other bosses a little too much

Sincerely we struggle to find a new enemy, a new object or even a new mode introduced by binding isaac afterbirth which really felt the need, despite something vaguely interesting there is (for example the new transformations).


Unfortunately, however, some additions break the balance that previously worked well, while others are completely free and out of context, despite the strongly surreal nature of the representation of the game.


For example  the binding , the dimensional holes, from which enemies come out on enemies until they are destroyed, seem to have been stuck to the whole without a real reason.


Moreover, they increase the difficulty a lot, often incorrectly since they can be in places difficult to hit. When you do not have adequate firepower and the room starts to crowd with enemies, they become particularly annoying. Worse still behaves the champion


Brownie, a giant poop boss who fills the rooms with leeches, make it almost impossible to kill him without taking damage in case you do not have a good stock of items.


Let’s be clear: The binding of isaac has always been a difficult game, very difficult, but at the same time correct, in the sense that it has always given the player the right legibility of the action, even in the most chaotic moments.

 Some new contents ignore this correctness to the point that it is to be thought that they were added just to make a number and without a precise project in mind.
