The two chapter "Watchmen: The End is Nigh" downloadable beatemups, released sometime around the movie, are being brought to retail disc for some reason. This move is most likely to capitalize on the DVD's upcoming release in July.
The game itself is actually fairly entertaining if you bought it. I myself played a bit of it a couple months ago and remember enjoying what there was. It's a very simple game at heart, however. Critical reception wasn't very kind to it, on the other hand. Many people didn't enjoy it for the same reasons I did enjoy it - it's a good game to turn your brain off too, because there's nothing to really think about except using your gloved superhero hands to beat some criminal.
