Yes, Free! By navigating to http://store.steampowered.com/app/35450/ and downloading the game tomorrow after the promotion starts and before it ends (the promotion will last 24 hours), the game will be free to keep forever!
Following this, we will be rolling into a free weekend for Rising Storm (free for a limited time) as well as a discount! If you’ve been trying to convince a friend to play Red Orchestra 2 with you, there will be no better time than tomorrow!
Hurry up and grab this one before it costs money again tomorrow!
