These are the first Max Payne screenshots that have come out in years. Literally! (Here's the last batch.) When last we heard, Max Payne 3 was originally scheduled for a 2009 release, but currently, Rockstar has not revealed anything about when we can expect to see the game. Your guess is (almost) as good as mine.
The shots reveal little if anything about the game, although they look a bit like stills from a trailer. I imagine we'll be seeing a lot of this kind of hint-hint release of stuff between now and E3, as game companies keep the hype machines stoked before the big reveals at the Electronic Entertainment Expo in June.
There's a second screen under the "Read More" tag.
