Oh puh-leeeeze.
Do you serously want all missions to look the same? Always in best gear and such? Seriously?
You'll note that I stated that other infiltration mission at least kind of fit in with x-com not using "their best gear". This fits in with beach missions not spawning units with rocket or grenade launchers. There is no reason as to why x-com should go in naked on this one. You are not facing a cult, you are facing a rogue element of an international weapons conglomerate. X-Com should not be dumb enough to send in agents in animal furs against guys carrying high-tech weapons and wearing body armor. Your entry even reads that these guys should not underestimated, even when outgunned.
I am not even going to respond to such a silly "issue".
This is valid criticism for a badly designed and thought out mission. Not only does it not fit in with other infiltration mission, it also makes x-com out to be amateurs - which at that point that are not. X-COM has at least recruited a military envoy by then. Somebody who would no doubt veto such an approach, being acutely aware what kind of forces X-Com agents will be facing.
This would go over as an april fools joke, not as a serious mission. The setup makes absolutely no sense, seeing how x-com has a plethora of other options that would not leave their agents as cannon fodder (seeing how using rookies on this one isn't really an option).
Well, they also use them, just not as often. They can't all be toting big bones and remain relevant...
So I take it that also also usually employ Dragonflies or Helicopters? If I was UAC I would probably hightail it if my supposed cavemen contact turns up in anything but land-based transportation.
I guess this mission could use some polishing, it was made under heavy time constraints, sorry.
I was not aware that this was part of the "crunch" - that explains the "hasty" approach x-com takes
If you have a chance to go over the misison and absolutely need to use the cavemen disguise, why not at least make it a bit more elaborate, seeing how this is the start of a bigger arc?
Why not approach this as an exfiltration mission instead? X-Com meets the contact+henchman in cavemen disguise, now you have to knock him out/capture him and exfiltrate him while reinforcements (i.e. UAC mercenaries who were standing by in case things go bad) arrive on the scene.
