This is exactly the problem, I don't like restricting my playstyle because of the mod, I don't find it fun to do so (the third one I never do though)
No offense intended, but that's like, I don't know, playing a chess computer, cranking the difficulty all of the way up, and then complaining when you lose because your favorite pieces are the knights and so they are the only pieces you ever move in the whole game. I mean sure, forcing you to play with
all of your pieces instead of just the knights could be considered "restricting your playstyle", but (to me at least) it seems like playing with just the knights, no matter how much you like them, is kinda stabbing yourself in the back anyways. You aren't experiencing the whole game, y'know?
Just my two cents, though yeah, feel free to turn on cinematic mode to make stuff lots easier if you want some more leg room; there is a reason why it's a second wave option after all.
Granted, I'm on my first run and I fucked up weapons research because I didn't realize how scarce fragments were, but I've been dealing with the purple bastards with battle rifles and grenades.
I ran into the same problem on my first run, and my solid advice is just to restart and save yourself the many hours of your loss slowly grinding ever closer. Part of playing tactically is making sure you stay on top of the research ball, and if you messed up too badly then you
will eventually reach a point where it becomes nigh-impossible to proceed because your weapons can't hurt them while their weapons one shot you.
goddamn fast. Enemy pods start getting more numerous and closer together right about the time thin men start showing up, and I haven't found a not cheating way to get to lasers/actualarmor before chrysallids start showing up, which is batshit.
I can assure you that getting at least a handful of decent weapons is totally possible to do by the time they show. IIRC in my last run-through I had at least basic laser weapons by the time they showed up (and honestly against chrysallids armor is pretty useless until the very late game). My biggest suggestion with dealing with them is a combination of two things though:
1) Assaults with shotguns, triply so if you can rush one up to get close combat specialist. Two assaults with CCS standing next to each other pretty much renders anyone in their sphere of influence immune to chrysallids for most of the early game, even with just basic ballistic weapons. You can't always have these by the first terror mission, but if you focus on at least one assault you can usually have one by the second one.
2) Grenades+Flash bangs. Chrysallids tend to run up as a group, which makes them perfect targets to hit with an explosive. If you still want the corpses you can even just lob a grenade or two at them to soften them up before you fight them, then finish them all off manually. Alternatively if you spot chrysallids far enough away a flash bang can really be helpful. At near max flash bang range you can buy yourself an entire extra turn to shoot them before they reach you, which can be very helpful.
Lastly just as a general tip (it actually doesn't really apply to chyrsallids
) I'd like to once more reinforce the idea that "firefight = very bad". Ideally you should wipe out an entire pod on the first turn. If you don't think you are going to have them all dead within a turn or so, consider retreating. Moving back out of their range and then letting them come to you (only to be riddled with overwatch shots)
is a totally valid strategy, and one that I personally have used many a time.
