Microsoft has announced that several new titles will soon be joining the ranks of the Xbox 360's budget priced Platinum Hits line. The new additions include some seriously heavy hitters, namely Grand Theft Auto IV, Street Fighter IV, Left 4 Dead, Star Wars: The Force Unleashed and Saints Row 2. Microsoft's announcement (oh so conveniently) neglected to mention prices for any of the titles, but a quick check around the ol' internet points to a price of $29.99 for most of the new additions (though SFIV curiously seems pegged around $40 for the moment). We should also point out that while these are some legitimately great games, both SFIV and Force Unleashed are receiving upgraded, budget versions in the near future -- Ultimate Sith Edition later this year and Super Street Fighter IV in early 2010. It's also worth noting Left 4 Dead is receiving a full-blown sequel only a month from now. Microsoft has also announced that retailers will be offering a "Buy 2, Get 1 Free" promotion for Xbox 360 Platinum Hits through October 31, though the release makes no mention of which retailers are doing so. We've contacted Microsoft for more information on the promotion.
