I'm on my first play through of enemy within and currently have a MEC unit and am aware that you can upgrade them using the rank, but I was wondering is there a way to either unlock additional armors for the MEC warriors or is there any upgrades that I can get for them in the foundry?

You can unlock stronger suits (more armor HP, bigger will bonus, extra equipment) by researching UFO Power Source and Titan Armor.

Several Foundry projects also benefit MEC Troopers:

  • This is first time that I've actually bothered with the Alien Grenades project... before MECs came along I just stole them off Mutons ;-)
