I have Iron Harvest, from one of the previous sales. It's...okay. It
looks awesome, graphically, and sounds pretty good as well, but the actual combat and damage mechanics are pretty annoying to actually play, in my opinion. It's a copy of the Company of Heroes somewhat hard counter damage model, with slow spawning times and capture of control points, with a cap on total number of defense structures you can build, as well as pretty low unit cap. Add that in with lots of siege type enemy units, and you can have decent army, but constantly have to run it back to defend your base if one AI controlled siege unit gets near your base (and can almost obliterate it in the time it takes to engage it). Split armies will of course lose to massed enemies, or at least be so damaged that you need to stop and repair/replace lost units.
I have yet to finish the campaign, because I got burned out on one of the limited unit story missions. Infantry is garbage, by the way, vs the mechs.
*EDIT* I loaded up Iron Harvest to check on my campaign and the new patch and... the new patch is incompatible with all old saves.

Not a huge deal, as I can restart the last mission I was on from the beginning at least, but pretty annoying.
