Biggest Bang Achievement won't unlock

[Boulette Cacahuète]

So yeah I did my second run of the game, beating it really quick to get the Biggest Bang Achievement which is my last one remaining, and when I beat the Joker at the end, my achievement didn't unlock.

But I also skipped the last cutscene where the hit is seen, maybe it is the reason ? Can anyone confirm if it's that, and if yes is there a way to unlock it ? I can't reload the boss fight...

Don't rush the game. The bug probably happened from you skipping the scene, thereby not allowing enough time for the reward confirmation. Similar flagset bugs have been logged across all Arkham forums caused by players exiting rooms or speed-skipping conversations before expository dialogue or displayed confirmations expire, such as the Hush room glitch in Arkham City or the Enigma server destruction in Arkham Origins.

If you haven't manually made backup saves then unfortunately there's no way to reload that fight. You'll either have to replay the game in Hard mode or download a Hard save prior to the boss fight or the Party Pooper encounter.

Yup, I redid the game without cutting that last scene and got my achievement. Thanks for the answer :)
