The given reason for this is that the cybernetic arms and legs made for off-duty hours aren't agile enough to be used. MEC Troopers are unable to be deployed onto the battlefield without their actual MECs, even though they always have a set of arms and legs available.It's a case of technology and necessity outpacing long-term considerations: MEC Troopers will never be human again, and it shows. While the description is probably meant to be hopeful, the fact that the base augments (the skeletal limbs that the MEC Trooper wears while not in an MEC) are intended to 'hopefully' allow the soldier to return to a normal life if XCOM wins the war, is kind of frightening.It is both heroic and scary at the same time. Instead, MEC Troopers are men and women that voluntarily amputate their own perfectly fine limbs and replace their organs with machines, just so they can have better combat effectiveness. The worst thing about them is that, unlike Space Marine Dreadnoughts or Protoss Dragoons/Immortals, it's not just critically wounded soldiers getting put into mechanical suits so that they can keep on serving. While the surgery isn't shown, MEC Troopers giving up their arms and legs, along what appear to other parts of their body, is horrifying to picture even if it is voluntary.While XCOM states that they will attempt to prevent it from happening again, the fact that Chrysalids could infect the oceans is pretty damn scary. This makes sense given the scene it looks like the ship crashed into the village, rather than docking with it. More frightening the text during and after the mission implies that this infection happened before they were fished up.Then, once you've managed to pull that off, Chryssalids start pouring out of the whale-hive, and you've got to make a mad dash back to the landing site before either the airstrike wipes you out, or the Chryssalids catch up.

Central makes it clear that you've only got one option: fight through the horde of Chryssalids to activate the boat's transponder so XCOM can direct an airstrike to wipe out the entire village. And more and more are getting birthed every round. You push through the village, to find a wrecked whaling ship, where the sharks and a captured whale are being used to incubate an army of Chryssalids. This looks bad, because where there's zombies, there's Chryssalids. You land at the village and start to progress through it. The regular military rescuers have gone silent. It's a Council Mission in Enemy Within where the team is dispatched to investigate a distress signal from a Canadian fishing village. With that in mind, just think about what happens to all the civilians that gets abducted, or the unpleasant implications on what will happen to the body of your fallen soldiers if you are unable to retrieve them due to the mission being aborted.

The description reveals that the soup contains unmistakable traces of human DNA.

One of the Vendor Trash that you can collect after capturing the alien base is the 'Alien Food', a nutritious slurry eaten by the aliens.

The tutorial, if you played the first game when you see the soldier in the warehouse, you just know he is gonna frag you, and there is nothing you can do to keep yourself from dying.

Your first encounter with a Sectopod would most likely involve a giant fucking laser coming out of nowhere.

The Sectopods have a long range, and it's possible that it can hit you without you being aware of its existence, because its attack range is greater than its sight range.

And the case becomes even worse at Site Recon. These guys just saw their friends get brutally mauled and now their dead friend is out for their blood.

This is extra the case when you see it through the perspective of your soldiers.

Huh? They killed a civilian, you say? What!? THE CIVILIAN IT KILLED CAME BACK TO LIFE!? They're also probably going to be the first time you'll meet the Chryssalids. In the background, you hear screaming and panicking crowds, air raid sirens wailing, police and fire sirens blaring, and the sounds of human and alien weaponry exchanging fire, while you're attempting to rescue an isolated group of civilians, who are being picked off one by one by aliens. Just what are they doing to the Mutons to get the information so quickly? Now, let's go to South America's continent bonus, 'We Have Ways', which allows all interrogations and autopsies to be completed immediately.

Remember those Mutons and how they're supposed to be the front line troops for the invaders? They can take some serious punishment, soaking bullets to the face, to say nothing of their elite counterparts.
