On this page of Batman: Arkham Asylum game guide, you will find out how long it takes to complete the story alone, side missions + main missions, and how long it takes to unlock all trophies in the game.
- Batman: Arkham Asylum offers players 10 hours of gameplay, focusing solely on story missions. It's not too much, although it should be remembered that there are also all kinds of collectibles, side missions, and a world full of thugs always ready to fight. A single playthrough time is also dependent on what difficulty level the player chooses. On higher difficulty levels, opponents deal more damage, and are harder to beat, which translates into the extra time needed to defeat them.
- Completing the game with all the main and side missions should take you about 15 hours. Of course, everything is determined by what level of difficulty you choose and how well you deal with your opponents.
- Earning a platinum trophy in Batman: Arkham Asylum is somewhat time-consuming, taking players up to 25 hours. Unlocking all collectibles and puzzles might sometimes prove challenging.
