I’ve been messing about with trying to prioritize Mimetic Skin over an early MEC. My reasoning was that I’d start in South America, so I could get Mimetic Skin immediately after killing my first set of Seekers, and the early stealth would make it easy to capture stuff, which syngerizes well with South America’s interrogation.
It didn’t work out that way. I just never seemed to have the money for a Genetics lab and a bunch of Skin. Skin’s pretty expensive for the early game at $75 a pop, a South American start is awfully short of cash, and it felt like getting squad size 6 was a higher priority than the first stealth soldier. By the time I’d finally gotten around to making stealth soldiers, I was pretty advanced anyway - lasers and skeleton armor. The real trick is finding strategies which improve survival before you get to squad size 6 and laser / medium armor, because that’s normally the turning point where squad wipes are unlikely.
One thing that skewed this a bit was that I advanced rather more rapidly than normal. I took Scientists first instead of Engineers because I wanted an early Arc Thrower, and I did capture a bunch of aliens early for some very helpful research boosts, despite not following through on obtaining Skin properly. Engineers first is the common wisdom, yet it’s not really that hard to end up with 10 Engineers early in month 2 for your second Uplink even if you don’t go Engineers first.
Maybe I should try it again, this time forgoing an early OTS for that first Skin soldier. That works for a MEC, since an early Sniper MEC improves your squad survival significantly, but a single stealth soldier is at least as expensive as a MEC, and doesn’t bring any more firepower or durability, just a probable first strike on a single alien. Which can be a guaranteed kill if the stealth soldier is an Assault with a shotgun.
Also, I’ve found that taking Close Combat Specialist on a stealth soldier is bad news. More than once I’ve had one reveal her position by taking a potshot at an alien that got too close. I’ve also had teammates blow up her cover during overwatch several times, leaving her visible and exposed. It’s a wonder she’s still alive.
Yes, it does. It’s usually not terribly important, though. The only time there’s a threat to your satellites is if you cannot take down a UFO. If it escapes, a little while later a battleship shows up and blows up your satellite unless you have Stealth Satellites. Presumably you can’t take on the battleship if your interceptors aren’t good enough to handle the earlier ship. Unless the timing is particularly poor, though, you can put up another satellite, and that will push the country in question out of panic-5.
It’s common on Classic and above. Lasers really aren’t that expensive to produce, and it takes too long to research Light Plasma Rifles on higher difficulties - by the time you’ve got the tech, you’ve taken serious losses because you’re trying to handle Mutons and Chryssalids with conventional weapons.
