Minimum requirements shown in the capture
The Steam capture lists 4 GB RAM, DirectX 11, a broadband internet connection, 2 GB available storage, and a DirectX-compatible sound card. Some operating-system, processor, and graphics text was incomplete in the supplied capture, so it is not reproduced as fact here.
Voice and connection requirements
A microphone is required to play. The note also says online multiplayer requires a permanent broadband connection, and strongly recommends headphones to prevent game audio entering the microphone.
Before installing
Check the live Steam requirements panel for the latest hardware and OS details. The official listing can change after updates.
