In Microsoft's first person shooter, Shadowrun, two sides -- the mega-corporation RNA and the ancient group known as Lineage -- battle to control magic. Players choose a side and a race (humans, trolls or dwarves) and embark upon an epic struggle for power in a world where spells and machine guns co-exist. In addition to the standard lot of pistols and sniper rifles, gamers use cybernetic enhancements to see through walls as well as magic to resurrect comrades, heal themselves and pass through solid objects. Each map supports up to 16 players (with or without bots), and thanks to Microsoft's Live Anywhere technology, people playing on their Windows Vista installed PCs can frag Xbox 360 users. Combine all this with cooperative mini-games, the ability to purchase equipment and system-link support, and Shadowrun may be one of 2007's biggest hits, providing its multiplayer component hides its limited single player offerings.
