Man this has been an awesome update!! I really can't wait to see more! The Minotaur really scared the crap outta me. I've also really been enjoying all the little bits of world building and such, in future updates I think it'd be really cool to see a world map for earth? Anyways I'd love to geek out more over the lore in future updates!
Also a few things to add on:
I think in terms of balancing some enemies or the MBT in particular should be able to see through the smoke, or just shoot wildly into it? And with the levels with water I was thinking that maybe the water can cool the rig more efficiently? I don't know how realistic that is though.
When I also first saw that weird bowling pin thing, I thought that maybe there could be a sort of Kamikaze drone enemy? Something inspired by maybe the Ohka?
And speaking of desperate governments trying to win conflicts, as the missions and war progresses it could intensify in scale and desperation? Turning from skirmishes to total war. We could see the arms corporations slowly run out of their MBTs, Minotaurs, Helicopters, until it's only footsoldiers with anti armour weapons, and shoddly put together mechs.
It could also add a moral aspect and as the conflict rages on, we're ordered not to do special missions where we're the one woman army, but instead going block by block clearing overzealous civilians, raiding food stores, and fresh water facilities. Or vice-versa, we could be the ones on the defense, defending key infastructure, even experimental facilities. Or is this getting a bit off track? Either way I can't wait to see where this where this game goes, I think you'll go really far!!
(Sorry if I nerded out a bunch, these kinda things are what I live for.)
