This is pretty easy and is nowhere near as tough as Red Revolution. As you begin on an island, you will definitely want to build a navy. Good air coverage is necessary again as the Allies will send rocketeers your way once more. They will also be using the chronosphere against you and as you never know where there going to jump in, keep a defensive force around your base (with some tanks please) and try to keep decent tesla coil coverage. I had a lot of success with Dreadnoughts and Kirovs on the Allied island. The northeast has a pleasing suprise for you - I found three Kirovs waiting for me there. Destroy any Allied patriot missiles with your dreadnoughts and keep the Kirovs away from the heat. Clear a path for your ground forces later, as you will likely have a long struggle trying to finish the chronosphere with Kirovs.You will have to navigate ground forces all the way north up the island and around to the center. I tore throught a lot of the base before losing my air fleet. You'll be experiencing very little mobile resistance after destroying so much of the base so your next priority should be to locate the Chronosphere. Use your iron curtain weapon on a group of apocalypse tanks and roll into the enemy base. Eliminate any ground resistance and prepare a large group of conscripts, flak troops and tesla troopers to destroy the sphere. I nuked the sphere itself, but it takes more than one and they will repair it. Instead use your nuclear attack on some of the prism towers or a concentration of enemy soldiers. Bring in your transports to finish off the chronosphere. Congratulations, you've won.
