If you have been following the coverage up towards the launch of Iron Man 3, then you would know that today is the day. Gameloft officially launched the Iron Man 3 game into Google Play, set at the reasonable price of free. I have not downloaded it yet (it’s about 750MB), but the game looks to be heavily based on the idea that you can use many different Iron Man suits, battling the baddies with different weapons.
The game is completely free from Play, but be prepared for an all-out battle with IAPs. From reading the reviews of the game, they seem to be everywhere. Not that this is a surprise though.
