Warhammer 40,000: Space Marine is on sale in the United Kingdom today, but those looking to get the game on Steam will notice that it's suddenly not on the storefront. The game recently blipped out of existence, and nobody's willing to give any comment on why.
Previous games to do this include Dragon Age and Brink, although Brink would later reappear. No idea if Space Marine is coming back, but PC fans can still nab a UK version via Direct2Drive and Gamersgate for £35. Interestingly, ShopTo.net is selling Steam codes for a very adequate £23, so that's an option too.
It still surprises me that we get issues like this. An industry as technologically cutting-edge as videogames and people still can't get their heads around the notion of a global market. International screw-ups shouldn't still be happening.
