Mednafen on Windows with TG16-Mini USB Controller. The main strat here was to prevent the enemy from taking any neutral factories. First I wanted to lure their Eagles over, surround them, and destroy them, which worked well. Then I wanted to use the Mule/Kilroy to take the top factory, which the enemy prevented. Finally, I wanted a Kilroy to take the bottom factory. The enemy slowed me down, forcing me to take the bottom factory on turn instead of 6. Then, I took a Pelican/Kilroys and made a run for the enemy base.

There are plenty of time saves still available for this map:

1. At least one turn save by taking the bottom factory earlier.
2. Not bothering attacking once the Pelican/Kilroy are out and on their way - their only risk at that point is that the Atlas one-shots the Kilroys.
3. More decisive movements.
4. I'm not sure if taking the top factory would speed things up (due to more units reducing the enemy units) or slow them down (more movements/attacks), but it would increase the likelihood of taking the bottom factory sooner via more infantry.
