Now, we know the release date, have the game, and can review it, but we're not going to. At least not yet.
See, there's a glitch in the version we have that causes the game to freeze if your PlayStation Network Friends list is full. Needless to say, this is a major problem. We've alerted Sony to the issue and have been told that developer Housemarque is working on a fix.
So, while we're allowed to review the game now, we're running into a game-breaking issue that could be fixed and consumers might never see. We're going to hold off. The official Dead Nation review will go up when we get a fix or when the game is released to consumers -- whichever comes first. When that happens, this article will turn into the review.
Expect drastically different scores depending on whether or not the issue is fixed because Dead Nation is definitely fun...when it runs.
