Historically, movie tie-in games have sucked, but it seems like that trend might ever so slowly be changing. Temple Run has produced a couple of fun movie tie-in spinoffs, the Guardians of the Galaxy mobile game is pretty good, and the new Teenage Mutant Ninja Turtles ($2.99) game seems really promising. Another good example is Glitchsoft’s recent Uncanny X-Men: Days of Future Past ($0.99). Sure, it might not change the world or anything, but it’s a surprisingly competent action platformer that does great fan service in the form of many playable characters. Today a new update has landed for the game that increases that number of playable characters with the addition of both Storm and Polaris. Here’s a short video showing off both Storm and Polaris in action.

In addition to the two new playable characters, Glitchsoft has tweaked how characters are unlocked in the game and now all characters are playable after completing Stage 3. Also, Uncanny X-Men: Days of Future Past is on sale for the first time since its release back in May, and can be had for just 99¢, down from its original price of $2.99. Also worth mentioning is that the game is following recent trends and doesn’t require an internet connection to play and does not contain any in-app purchases. If you’re an X-Men fan, it’s definitely worth checking out for a buck.
