Senior gameplay programmer Paul Denning says“I think Arkham Asylum has almost run its course,” said Denning in PC Zone Magazine’s recent retrospective on the original game. “We did pick a selection of buildings that we thought would fit the original game well. You could quite easily point out that there are various things that you wouldn’t usually find in an asylum especially on an island that’s supposedly self-contained.”
“Gotham itself is a fantastically realised fictional city,” he continued, “and there are so many places that would be probably be ideal for gameplay and great to explore.”
Though the developers don’t plan to go the open-world route, the chance still exists that the Joker will escape in the next game.
