Arma 3's April Fools joke raises serious cash for the Red Cross

Arma 3 Karts began as an April Fools' Day joke that turned into downloadable content and earned 1 million Czech koruna (about $49,621) for the Czech Red Cross, developer Bohemia Interactive announced today.

The kart racing offshoot of the military shooter is part of Bohemia's plan to experiment with DLC. Released late last month, the Windows PC add-on content is available now for $1.99 on Steam and on Bohemia Interactive's store.

"Alongside helping us to evaluate Arma 3's new approach to DLC, with the backing of our community, Arma 3 Karts has managed to raise money for a great cause," said creative director Jay Crowe. "A big thanks to our players, both for their support and their valuable feedback, which we'll use to refine our implementation. Overall, we're positive about the preliminary results and responses, which seems to benefit Arma 3 players and help sustain Arma 3 development."
