To celebrate the fact that they’ve been around for 15 years, developer Bohemia Interactive has launched a Steam sale and they are also offering a free game. The Bohemia Interactive Weekend Sale on Steam offers games up to 80% off and some of the games that are part of this sale include DayZ, Arma 3, Memento Mori, Alternativa and Take on Mars, among others.
Additionally, military sandbox game Arma 3 will be available as a free title during the weekend (from May 15th until May 18th, to be more precise.) If you like the game and you want to continue playing it, you can get it 40% off its usual price, since the popular first-person shooter is also part of the weekend sale.
Finally, Arma: Cold War Assault (originally released as Operation Flashpoint: Cold War Crisis in 2001) is available for free, but it’s worth mentioning that you need to download the game before the end of the weekend to keep it in your Steam library.
