4 Good gameGrafix | 07/10/2011 | See all Grafix's reviews (6)On launch day there was a huge mass of bugs apparently, as you can see from the review by 'COD4Fan'. However, the developers insisted it was due to drivers. I have not experienced any problems and neither has my friend who I have co-op'd with. Great fun on co-op playing together. As for single player, I haven't played that yet.Don't let all these 'bug' reviews/comments stop you from buying it, seriously. Most people I know worked it out within 10mins and all of my subscriptions on YouTube, they sorted their game in minutes as well.You like the look of it? Get it.
