Appearing on Xbox Live Arcade tomorrow will be Voodoo Dice and Doom 2.
The former is a puzzle game by Ubisoft that costs 800 Microsoft Points (£6.80/9.60). Up to four people can play. We know little more than that; there are some pictures on the Xbox website.
Details are equally shady on Doom 2. But in Nerve Software - developer of the brilliant Doom XBLA remake - we trust. There's no mention of a price, but we expect the same 800 MSP price-tag that was used for Doom.
