Reddit user S282 posted a collection of Batman mods to the community-driven news aggregator for the open-world crime game Grand Theft Auto: San Andreas. The add-ons (which can be downloaded here) transform the west-coast metropolis into a decent approximation of Bruce Wayne's Gotham City. Virtual caped crusaders can drive the Tumbler, glide with the cape, and run from the GC police department's patrol cars.
I'm in the midst of total-Batman-immersion therapy. I'm reading many of the Frank Miller comics for the first time. I'm halfway through Arkham City, and I even downloaded the official Dark Knight Rises game for Android. No amount of Batman is too much Batman for me…and I'm glad I live in a society that doesn't immediately commit me to a sanitarium for admitting that publicly.
While this is a collection of different mods, you can get a taste of what's in store by watching a trailer for the The Dark Knight Begins add-on, which acts as the base for the S282's entire collection.
