Reviving the long-lost Borderlands MMO may be one modder's "biggest challenge ever," but they're already eyeing up another that's even "harder to obtain" – a web browser game killed in 2012 called Mount Jackmore

Chances are that unless you're a Borderlands mega fan, you'd probably never heard about Borderlands Online until very recently. The long-forgotten MMO was slated for a China-only release when it was announced in 2014, before being killed off for good in 2015 alongside 2K China. However, one modder and dataminer has been leading the charge in a huge effort to get the game playable again, and they say the project has "consumed me."

Modder EpicNNG – known as Epic – brought Borderlands Online back into the spotlight around a month ago with footage of the game running for the first time since its shutdown. Stuck on its character creator screen, admittedly, but that's further than anyone else has gotten in a decade.
