I got to try the demo of this game on xbox. Whilst the story seems like an enjoyable Indy inspired romp, this game suffers from many technical problems, which put me off from owning it even on novelty factor.
However, a pc version does exist (and would fix many of those things). Also, a ps3 version will be coming out down the line that is said to be a superior version, which enhanced visuals, more levels etc.
The multiplayer did seem a little more inspired then the likes of tomb raider and uncharted, but again it all technically falls flat.
A shame really. The gameplay didn't interest me either, especially with the poor implementation of alan wake's light mechanics.
Overall, it's an adventure-inspired game, I didn't come in high expectations, it could've easily been legendary if it were the 'Jack Hunter' or 'The Librarian' of adventure games. But alas, it's more like 'Alan Quartermain and the temple crystal skull" or Sinbad starring Lou Ferrigno xD
