Releasing on the PS3™ and PC on Sept 28th, sign up for a chance to get early access to the PS3™ and PC trial mode versions.
Lara Croft and the Guardian of Light is the first ever co-op multiplayer action adventure game featuring Lara Croft. This brand new downloadable adventure combines the hallmarks of the Tomb Raider franchise, including exploration and discovery, platforming, and puzzle solving combined with character progression, fun fast-paced combat, and elements of human cooperation and competition.
A (UK.)GameSpot.com account will be required in order to take advantage of this offer.
Although the offer makes reference to the US, I have just gained a Redemption Code for the PS3 & if I had enough space on my hard drive (sigh) I would now be downloading the 1-2 players / HDTV screen resolution: 720p / 2343 MB trial version of the game.
