Took me a while to respond, I was working on
graphic resources for the Commercial tileset and you know how it is... I need a break from FMP once in a while.
As for the aliens' appearance, it's largely a matter of random numbers. Each campaign is different in this regard; sometimes I mostly fight Floaters, and another time I almost never see them. That's normal.
Hobbes' novel can be found
here. Read it.
Also it helped to tweak the Xcom1 and Final Mod .rul files in respect to facilities and Xcom craft and intial starting stats of troops.
Care to elaborate on what exactly you changed? I'm curious!
Once you get the Elerium Mace you basically need to zerg rush aliens (I had to use this over the dart rifle as I couldn't for a long time get any of the upgraded clips) you basically have to not care about your soldiers and capture as many as feasible.
This is much much easier in confined spaces (like UFO's/bases etc.) until you get engineer's then they unlock some sort of ocular implant research for plasma weapons I'm not sure what other research you need to get this but this is what opened it up finally for me.
For a long time I was just using Gauss weapons.
Ethereal's are just insane you basically have to hide your entire squad in the sky-ranger and pray your HWP's can clean up the outlying ones so you can capture some inside the UFO's and zerg rush stun them (sometimes these bastards take three stun hits)
Once you get the psi-amp though and train up some strong psi users the game becomes exponentially easier to mind control / drop equipment and capture.
Yep, all valid tactical advice! Though it should be added that the Stun Rod, while weaker, has one advantage over the Elerium Mace: it always hits.
And man, kudos for even fighting Ethereals with no decent weapons...
What's happening with the Alien Data Slate, seeing this remains researchable forever with one item with the latesst version you uploaded?
It appears that you need to enable the "item is destroyed on research" option to prevent this cheat. I need to include it in the mod description.
