With Iron Man 3 in cinemas, here's a tie-in game for mobile devices. It's essentially an endless runner (or flyer), with Tony Stark as Iron Man soaring through different levels, collecting credits and power-ups. There are obstacles to avoid: inanimate objects such as planes and buildings, enemy obstacles such as missiles and explosive devices, and enemies that will try to shoot you down. Take too many hits and your level is done. But if the damage is too severe you'll have to wait to have the repairs finished, a process that can be sped up with gems you earn by levelling up.You collect points to upgrade your armour and weapons, but there are in-app purchases that can get you those premium items quickly, ensuring your progress through the game. There are up to 18 different suits you can research and develop, each from the different Iron Man movies. Much effort has gone in to developing great graphics and environments; you'll find your- self getting a little distracted as you fly. Iron Man 3 is as addictive as games such as Temple Run ; you always want to get just that little bit further.
