Commandos Strike Force Announced (Xbox)

Pyro Studios abandons the RTS approach and is making a Commandos FPS.

Eidos announces the return of the legendary Commandos in the World War II, first-person shooter: Commandos Strike Force.

Commandos Strike Force takes you right into the heart of the action from a first- person perspective giving you control of the three members of the Strike Force unit. Switch between the Green Beret, the sniper, and the spy, but plan carefully, as you will only succeed by combining each of the Commandos' unique skills.

Set in war-torn Europe amid the backdrop of World War II, you must take your elite group of Commandos behind enemy lines on a series of linked missions through France, Russia, and Norway. Destroying a Nazi ship, ambushing enemy troops, freeing French Resistance prisoners, and kidnapping a general are a few of the many missions. In addition to a compelling single-player campaign, Commandos also features a variety of original, online multiplayer modes.
Ignacio Perez, CEO of Pyro Studios says: " By combining the tactical approach of the previous Commandos games with the intense action of an FPS, Commandos Strike Force will provide a more cerebral approach to the wargame genre. Strike Force is our most ambitious project ever, and we believe that this game will set a new benchmark for World War II video games."

Mike McGarvey, CEO of Eidos says: " The Commandos series has established itself as one of the most popular and enduring franchises within the World War II genre. With this evolution of the series, coupled with Pyro Studios' proven expertise, we are confident that Commandos Strike Force will be the greatest episode in the series to date."

Commandos Strike Force, developed by Pyro Studios, will be released worldwide in spring 2005 on PS2, Xbox, and PC.
