What's New in the Extended Demo?
The extended Earth vs Mars demo features the first five missions of the campaign, the most complete look yet at the start of the Martian invasion. As the Global Military Alliance rallies to defend Earth, you’ll join Colonel Marcus Shaw, a determined commander leading the counterattack, and Annabel Corman, the ex-GMA engineer whose Splice-O-Tron technology may be humanity’s last hope.
This demo marks your first encounter with Emperor Zarb, leader of the relentless Martian forces. The demo now also features tutorials, updated UI with more detailed unit information, improved production menus, and a fully voiced experience that brings commanders, units, and story moments to life.
