Hi, In "Titan Commander" you can choose between 5 Commander in the form of Titans. 1. Atlas 2. Ares 3. Zeus 4. Helios 5. Ragnarok The all have the same characteristics as the normal Titans. I have added anti air. You can build anything that can even build the commander. Helios: You have to turn on power in order to build. Ragnarok: produce: energy: 4000 metal: 40 construction demand: energy: 2000 metal: 30 Have a longer build range. 30 minutes to the weapon begins.
