Some new things available for construction here, and you'll probably like them both. Especially the spy satellite uplink - you can see the entire battlefield. Mirage tanks are pretty impressive too. Equally powerful against infantry and tanks, they cloak too! I think the computer even has a hard time targeting them? Not sure about this, but yeah, they can die like any other unit despite this ability. Seeing that you start with an MCV I sold everything at the base I started with and relocated everyone outside einstein's lab. It seems easier to defend too as the original base is vulnerable from all 4 sides.
Starting base construction over was a pain, but you start with plenty of units to defend as you are doing so. You may find it prudent to build a couple patriot missile launchers near Einstein's base as it is vulnerable from the annoying V3 rockets. Keep those mirage tanks around the base to do the defending, they'll really do the job once they're elite. Once my base was functional I created about 4 prism tanks and 6 mirage tanks, a medium size group of GIs and a couple seals for good measure. This was pathetic how easily I won. I think I got lucky and did things fast enough that the Soviets hadn't built up a decent force with apocalypse tanks. Regardless, each of the three bases fell and I was victorious. Just keep everyone back, defending the prism tanks and you will be too.
