Really intrigued by the idea here, but wasn't able to really play it. Couldn't figure out how to make my mechs attack the enemy, and they didn't seem to be attacking me much either. Would to try a fixed up version!
Your mechs will attack and destroy any hostile mechs they're close to - it's not communicated very well and the TTK is probably too long.
Your own mechs/carrier doesn't take any damage at present. Hope this helps clear things up :)
