Space Marine 3 has started development. As confirmed by Focus Entertainment Publishing, Games Workshop, and Saber Interactive, work on the next instalment in the Warhammer 40,000: Space Marine has begun.

Despite the third game entering development, Saber Interactive is keen to make sure that players of the second game are not left behind. While Space Marine 3 starts its journey to release, Space Marine 2 will still be supported with a host of post-launch content.
