Independent developer Rebellion's Sniper Elite franchise has reached a new sales milestone.

　　The UK-based studio on Wednesday announced that the series has now passed 10 million copies sold worldwide. The franchise debuted in 2005 with the original Sniper Elite. Sequels V2 and V3 were released in 2012 and 2014, respectively. Check out the video below for more on the milestone.

　　"Whether you've bought one or whether you've bought all of our Sniper Elite products, thank you very much for supporting indie development in the UK," Rebellion CEO and co-founder Jason Kingsley said. "It's been a pleasure to deliver great games for you and hopefully we'll go on to do more in the future."

　　2015 marks the 10th anniversary of the shooter series. To celebrate the birthday and the 10 million sales, Rebellion is holding a month-long celebration that will include livestreams, giveaways, and more. Rebellion has also marked down the three core Sniper Elite installments by 80 percent on Steam.

　　Rebellion's next game, the Sniper Elite spinoff game Zombie Army Trilogy, was released in March. No future entries in the series have been announced.
