I basically stopped playing in 1998 just after entering Alien dimension. Returned in 2005 and made short work of the Aliens, until I quit again because the final mission was a bit too much to handle. So today at my third attempt (with same saves I've been carrying this whole time) all my wisdom accumulated of the years still proves insufficient to beat the last building.
There is a catch though, I probably could beat it - I just don't want ANY injuries... Unacceptable.
My soldiers (20) all have Disruptor Armor with Marsec torso (flying), Devastators, Cloak and 2x Shield. Four guys have Dimension Missile Launcher instead Devastator. Total cookie cutter, no brain cells required, killer squad - until this last mission. The problem is on the open fields Aliens eventually just spam Dimension Missiles beyond visual range (despite cloak) and I can go F myself. Getting mind controlled don't help either. Feel totally powerless. Turn based is even worse. Game is beaten in every other way, money is non-issue, everything is researched, etc.
Is there a way to cheese through this? Specialized gear perhaps? Go wild, Thanks.
Using all Disruptor Armour (rather than the Marsec chest piece) significantly improves survivability vs. Dimension Missiles. With all Disruptor Armour, you can shrug off half a dozen direct hits (they'll still take out shields, though, so an Entropy Pod is bad news).
Toxin B and especially Toxin C are far more potent than Devastators due to both simple firepower (one-handed gun, and fires 5x as fast as the Devastator) and the fact that they go through shields. Skeletoids usually get one-shotted by Toxin C. This matters even for stopping their BVR fire, because the AI doesn't cheat; they need a spotter just like you do.
The other trick to that mission is simply to speedrun it. The objectives are right in front of you and you only have to blow up half of them; you can win the mission within a minute if you put your mind to it.
I've beaten that mission via killing all aliens with toxins, and without toxins I've speedrun it (that was harder). I was using larger squads, though (24 or 28).
Also, yes, getting hit reveals cloaked units. This applies to you and to aliens.
EDIT: Toxins also make Psimorphs cry, because they bypass your shields without damaging them and then bounce off your armour (all X-COM armour has a 70% resistance to toxins).
