Today heralds the start of an intergalactic war the likes of which has never been seen before. Players will be thrust into the heart of the action as they don the legendary armour of the Ultramarines Chapter of Space Marines and fight for their way through this challenging demo for upcoming PSP title Warhammer 40,000: Squad Command. The PSP demo is available to download from THQ-games.com.

The demo gives players a taste of the fast paced strategic action and futuristic weaponry fans of this series have grown to know. Gamers are thrust into the heart of the action as their Chapter battles to save the planet of Ruhr III from the grasp of the daemonic Chaos Space Marines.

Players are given command of a small squad of five Space Marines as well as a heavily armoured Dreadnaught to complete their objective. These units showcase some of the 20 types of weapon on offer in this title as well as the player customisable equipment each unit can carry.

The complete game will feature a gripping and immersive storyline spanning 15 single player missions set in vivid 3D environments with destructible terrain and customizable units. Players will also be able to enjoy over nine unique multiplayer maps as either Space Marines or the corrupted forces of Chaos with up to seven opponents from across the globe.

The full version of Warhammer 40,000: Squad Command will be available for Nintendo DS and Sony PSP in November.
