The auction is taking place here on Flippa. And only a couple days left...
This is an auction for the website BulletstormForum.com (as well as the accompanying WikiBulletstorm.com, and a host of domains related to the game and any future sequels).
BulletstormForum.com is the largest fan forum for the game and brings in thousands of visitors daily. The game has received brisk sales (940,000 copies) in a little over 2 months and has been received well critically.
Considering the recency of the release and a cliffhanger ending that demands a sequel, there is huge opportunity for growth here.
The forum was built from scratch and the posts are all real. We just topped 5,000 members this week, and are still getting lots of new members.
