Iron Marines

The first two stages of the Mr. Robo070 are relatively easy. It's important to build up your Refinery defenses during these stages, because if you lose both the game will quickly be over. I found that using a combination of Diplomats, Channelers and Rangers/Snipers to attack Rob070 works best. Diplomats protect your hero and soldiers from the laser fire and Channelers seem to do the most damage to Rob070. Snipers are good because you can quickly turn their fire towards any robots attacking your Refinery if you find it being overwhelmed.

The Doctor (a reference to the television series Doctor Who) can be found hanging out in his TARDIS to the right of the first Refinery in Mission 11. Just tap the TARDIS to complete the "I'm the Doctor" achievement.
