Red Dead graphics are quite nice and they are themed in the old style grainy western pictures with the same chunky graphics seen in grand theft auto series.
Now this game has loads and loads of unlockables which some can be bought are awarded based on how well you complete a level
The game has 27 levels, and about 15+ weapons with different characters to use as well, you can even ride a horse and blast people,
here's the sort of levels you get to play shootouts in various settings from ranches,ghost town, mine, forts + plus many more, train jumping (on and off),duelling ,bar fight,Indian stealth level and a great cannon blasting bridge level
Now once you complete the game a new level selector (bounty hunt i think) appears in the menu which gives you tasks to complete on each level i.e. complete within a time limit,don't get shot, maxout your kill combo bonus score, to unlock more even more stuff
The game may not be to everyone's tastes but I love it at also has a great multiplayer shootout which also works with Xbox live, with a choice of loads and loads of characters (about 50 easy) to have great shoot outs with your mates or online
This is a great game and lots of fun, highly recommended by me ye hah :)
