So I caved and grabbed LW 14f. Since this sounds like a total conversion, what should I look out for that's significantly different to vanilla EW? (besides the many, many points raised in this thread re: fatigue)
A few things:
1) Long war will, at times, throw missions that are virtually impossible to beat. These are the missions that you will want to turn down or retreat from, and learning when you need to perform a tactical retreat is an important part of the mod. Some missions just aren't going to be able to be won until you are much more developed.
2) Meld, while still fairly important, isn't necessarily a "you must grab the canisters" thing. If they are grabbable then grab them, but don't put yourself in a bad situation trying to get one. Long War is much less forgiving than default and you can easily get wiped, which can severely hurt you in the long run as well. Meld will show up just passively from gathering corpses in long war, and the farther behind you fall the more the canisters you do grab will contain, so don't sacrifice the mission for the meld.
3) All the SHIV's. Use them, love them, upgrade them. They are very, very useful when addressing fatigue problems.
So Brazil just got hit by a terror mission (and will probably end up leaving XCOM unless I get an abduction or something to drop the panic there). I start the mission, take a few turns, then trigger
every single enemy on the map simultaneously. The three chryssalids trigger my close combat specialists and are insta-wiped, but the remaining forces consist of 2 drones, a Cyberdisc (when I forgot to bring HEAT ammo), some 8 floaters, 2 mutons, and a muton berserker. The next turn the floaters deal a bit of damage, and the berserker charges in and instakills my sniper (he was a gift from Brazil in exchange for a floater prisoner) through the cover, causing my lead assault troop to panic while she's standing in the (now coverless) area.
Fully expecting a wipe at this point (heck, the cyberdisc alone could do it at that point) I annihilate the berserker, when the weirdest thing happens. All of the aliens just sort of... stop
. The only one that is doing anything is the cyberdisc, which is still going on overwatch every turn (but doesn't have covering fire). They aren't even shooting at my coverless assault troop. Not wanting to ruin a good thing, none of my guys move except for my two troops with laser rifles, who proceed to take the next 25 or so turns to kill every single enemy while they just stood there, not even on overwatch, shooting gallery style. I like to think that the Brazilian sniper sacrificed himself to buy a miracle from his country.
