Resistance 2 isn't a game that's full of bugs and the like, however there have been a few issues with trophies not being given when the requirements are met, and then there are some stat related bugs to be noted. Insomniac have as with Resistance: Fall of Man continued to support the game and release another patch for the game fixing many of the issues players have been encountering. And some more good news everyone; the option to save the second player’s character progress? Insomniac now have that firmware and are currently working to implement the feature.
