This week's Humble Bundle focuses on the work of Bohemia Interactive. The pay what you want tier gets you Arma 2, Take on Helicopters Bundle, OFO: Afterlight, Alpha Prime, Arma: Gold Edition, Fish Fillets 2, and a bonus game. Beating the average of about $4 gets you those games plus Arma Tactics, Arma 2: Operation Arrowhead, and three pieces of DLC for Arma 2. If you've ever wanted to try out the Arma series, this looks like the best possible time to do so.
