Natural Selection 2's first seven days, since crawling out of the development ooze and onto Steam, have been good for the game. It sold 144,000 copies and earned developer Unknown Worlds over $1 million.

"It has been a success beyond our wildest dreams," the team at Unknown Worlds wrote, sending out a sales infographic, which can be found after the break. "We spent the days leading up to launch dreaming of cracking the top-ten top-sellers on Steam. We ended up staying at number one for 36 hours."

The company will hold its first post-launch competitive event tomorrow, November 10, which you can watch on Twitch.
