Secret Mini-Game and Trophy
Unlock the IGOR armor and acquire all in-game achievements. Next, play 50 games with the new armor equipped, then close the app. When you open it again, the "Options" bar on the main menu should be glowing. Open it and you'll receive a trophy, while also gaining access to a special mini-game.
With multiple enemies on-screen, paint your targets by carefully sliding a finger across each bad guy.
Quick swipes usually result in misses.
Keep an eye on the obstacles that lie ahead. This will give you a much better chance at dodging projectiles.
Be sure to pick up as many Stark Credits as possible, and but avoid going after hard-to-reach virtual currency the developers strategically placed close to obstacles.
During play, be on the lookout for power-ups scattered along the track. These include the Fusion Charge (red arrow) that lasts three times longer than usual, the Alpha Duplicator (yellow x2) that quadruple's your score and the Proton Field (green shield) that lets Iron man resist three hits. Keep in mind these are only temporary.
It's always a good idea to have more than one suit researched to eliminate waiting for repairs to finish.
Complete achievements to earn Stark Credits and ISO-8. These include defeating 10 enemies in a single run or traveling 30,000 meters.
You receive the Mark III armor right away. From there, you can research up to three additional suits. Want more? Buy storage for 70 ISO-8.
You can unlock armor by spending XP or ISO-8.
Spend Stark Credits to upgrade Iron Man's armor across three categories: Special, Weapon and HP. The price goes up each time you continuously upgrade one of these attributes.
