12 Things You Didn't Know About Batman: Arkham Asylum

10. Only 40 Developers Made The Game

Speaking of the development team, Rocksteady weren't exactly a huge, experienced studio when they took on Arkham Asylum.

In fact, they only had one other game to their name at the time, a decent first-person shooter called Urban Chaos: Riot Response.

The team was also only comprised of 40 employees, which even at the time was incredibly small. Now, Rocksteady has over 200 employees, showing just how much the team has expanded, and how much their resources have grown, in the ten years since Asylum's release.
