The next major game in the Planetary Annihilation universe, Industrial Annihilation combines the iconic real-time strategy of the beloved Annihilation games with deep factory-building to deliver a blend of genres unlike any you’ve experienced before.
Just go for Beyond All Reason. It’s free and a much better clone of TA.
As a TA veteran, I could never get into Planetary Annihilation. Supreme Commander 1 & 2 were pretty good, got lots of hours in those.
Supcom FAF is still one of my favorite games!
