It's now been nearly 30 years since the release of Dune 2 for MS-DOS, the game that many describe as the first archetypal real-time strategy game. What better way to celebrate that occasion than with the release of the latest RTS in the Dune franchise, Dune: Spice Wars. Shiro Games and Funcom announced on Wednesday that they're ready to release the early access version of Dune: Spice Wars. The 4X game based on Frank Herbert's popular Dune novels will be playable on Steam starting April 26.
