Argh, I can't hold it anymore. How am I supposed to get alien food and alien reproduction using only Earth weaponry when assaulting an Alien Base? Like man, I skipped first two terror missions just because I have no good weapons to kill terror units. Cyberdiscs are PAIN. There are usually 7-9 cyberdiscs per terror mission and I am obligated to use HE packs to destroy them reliably. Tasers won't do anything, stun prods as well. Carrying rocket launcher with an elerium rocket seems useless as you are not guaranteed to kill a disc in one shot and also they weight a lot.
Man, I like how difficult XCom became with this mod, but this is just ridiculous. I can literally kill floaters, snakemans or sectoids for hours without a single loss, but should a cyberdisc appear and I am done for. Cyberdiscs are like sectopods in original game but at least sectopods had their weaknesses. Cyberdiscs for now are just overly tough and you are forced to deal with them using special weapons, which you bring just for the sake of killing cyberdiscs. And actually I see only two ways of killing discs: HE packs and rocket launcher. Alien grenades can cripple a disc quite a bit, but for most part you will need at least two alien grenades to bring one cyberdisc down and you need to throw them subsequentially as the explosion of one grenade destroys another. Heavy cannon won't do a thing, I managed to bring only one cyberdisc after about 15 hits (I play with TFTD damage formula) with AP. Rocket launcher is a better way of destroying cyberdisc if only it wouldn't weight so much that you need to either switch to lighter primary weapon or just sacrifice some cannon fodder. Also I found out the hard way shotguns are awesome for cyberdiscs as well but a little problem with that - cyberdisc explode if they are killed with anything but explosives or not stunned.
My rage is out.
Also chryssalids are pain too, but not as much as cyberdiscs. At least chryssalids don't explode and don't have resistances to common weapon.
