Well I started again on Superhuman. Lost my soldiers and Skyranger in the first fortnight and there's no easy way to come back from that when you've spent all your money already, so did a restart (I don't think that was cheating?).
Now in March, back to where I was on my Easy game - nearly researched Avenger, got Power Armour at least for my guys and gals, just about got Heavy Plasma, stumbled across Alien Base 1 so I can now do some harvesting of my own
I did have to withdraw from a Terror Mission in the first month as my soldiers weren't equipped for Cyberdiscs, but the game fortunately threw me a Floater-only terror mission in Feb which was a lot easier (though all civvies died and one by my hand so scraped a Poor rating there).
I expanded the base so fast I'm in a financial deficit so have been balancing building useful items with medikit sales to keep in the black - can't remember what financial woes trigger losing the game so I sacked a few spare soldiers and a second Skyranger that was mostly ornamental in its hangar - hopefully that will help.
All good fun but remembering how much the aliens cheat is also part of the fun (night vision, knowing where you are after X turns etc).
