THQ's Red Faction: Armageddon demo is now available for download on Xbox Live.
In the trial players will be able to battle aliens with the Nano Forge and Red Faction's signature weapon, the Magnet Gun, the publisher says.
The official description reads:
"In Red Faction: Armageddon, harness the destructive powers of the Nano-Forge to transform the world into your weapon and bring it crashing down upon your enemies. Your journey will take you from the frozen poles to the molten core of Mars as you wage war against the Red Faction's greatest enemy yet."
The full game's out on 360, PS3 and PC on May 31 in the US and June 3 in UK.
PlayStation 3 and PC demos will presumably arrive later.
