One tip for the final Nod mission I would have wanted to know before playing it - the game tells you that you have time until the GDI station makes three orbits and then gives you an hour timer. I was running out of time and made a despearate push for the final objective with just seconds remaining and then... another hour timer started. You have 3 hours to beat that map, I thought it was just the one =/

It's the finale where you have all the toys and get to play with the enemy in any way you want. Don't make the same mistake as me and rush through it, you can take your time.
