All EA's games are friends, which is why a code is being included in Dead Space 2 that will unlock armour in Dragon Age 2.
The armour belonged to Ser Isaac of Clarke, whoever that is, and comprises Ser Isaac's Boots, Ser Isaac's Armor, Ser Isaac's Gauntlets and Ser Isaac's Helm.
The boots and gloves give a bonus to overall armour; the chest-piece and helmet have an empty rune slot to fill; and the helmet also boosts critical damage. All pieces require high Dexterity and Cunning to wear.
"The chilling tales of Ser Isaac of Clarke are a favourite of bards performing in the wee hours of the night," prosed the Dragon Age 2 website. "In dank taverns throughout Thedas, these horror-filled stories captivate listeners and bring nightmares to those faint of heart."
BioWare pulled a similar stunt with Dragon Age: Origins and Mass Effect 2: the former unlocking Blood Dragon Armor in the space RPG.
Dead Space 2 is tantalisingly close. Look out for a Eurogamer review soon.
