I recently managed to win the game in Euclid (Medium) difficulty level. Looks like the hardest thing is surviving the first 3-4 waves in order to kickstart Production (Refine Duplication and Crystal Fractalization are probably among the first upgrades that you should get). In this way you get stabler sources of money and the game starts being manageable, but you must always be on your toes, because a small distraction could be fatal.
I wanted to achieve Military Might and Basic Weapons also in Euclid mode, and I did - but unfortunately, the game has no way to track this if you already got Military Might and Basic Weapons in Safe mode. So I'm not even sure if I really got Military Might and Basic Weapons in Euclid mode, because it's unfortunately very easy to click the wrong button by mistake (it happened e.g. when I tried to achieve Sacrifice in Easy mode: at the end of the game, I was not awarded it, probably I clicked Retreat once by mistake, maybe I clicked it instead of the scrollbar).
What is the hardest between Military Might and Basic Weapons? Hard to say, both have their pros and cons. In Basic Weapons, it's good to focus on genetics because you don't have to upgrade every single type of military unit, you just crank Aggression and Endurance; on the other hand, I really miss some tactical military units, especially shields and snipers. In Military Might, the good thing is that you can completely forget about Essence and Genes, so you can pump up crystals and cores like there is no tomorrow; on the other hand... well, duh, no big beasts, you'll have to sacrifice units more often. So, in the end, I'd say Military Might is a bit harder than Basic Weapons: what do you think?
Speaking of milirary units, some things that still bug me:
- it's hard to balance the relative speed of the various military units, and for some units, you can't increase the HP without also increasing the speed (and for some of them, you can't even increase the speed). So, sometimes you end up splitting your army too much, which leads to complete failure.
- Shotguns. I never used them, because they seem to suck, or I suck at using them. I'm curious: do other players use them effectively? if yes, how?
I still hope developers will show up again some day ... meanwhile, Merry Christmas everyone!
