Sort of, but it's no where near as good. Once you research Plasma tech after talking to Martians you can get your people (or allied Martians) to use plasma cannons, but they don't set people on fire, just do fire damage... plus take forever to aim, and then ready between shots. The 'plasma shot' mode that throws balls of plasma also gives a slow moving ball that takes forever to reach the target, and is a small explosion area. You pretty much always miss any moving target except at close range! The Plasma throw (flamethrower mode) is a little better, but still very slow to aim and you get three shots per clip! I'm doing a mod at the moment where one aim is to make Martian EM and Plasma weapons more accessible earlier in the game (because by the time you get them most enemies are either immune to EM or easier to kill with other weapons) and also makes plasma weapons more deadly, both robot mounted and hand held martian versions. I also made them set people on fire, though not quite as easily as the ALTR flamethrower and not for as long.
As to the 'follow this guy!' thing, I think it has to do with how much you carry, or what you carry. On different missions certain enemies (like rollers and elementals) will just follow one person round the map, but it changes as to who gets followed. I suppose it could be the level, ie follow the highest level person. For me it's usually Samantha, but then I usually get her to have dual pistols and tons of ammo so it might just be her load out.
Gatlings don't hurt them? That I haven't come across. Usually Gatlings mess them up at close range for me. Usually if I use Gatlings it's one guy, with a couple of flankers with rifles on aimed burst. Bear in mind the more kills your guys have the higher their accuracy is, no matter what their stats are. Often I make sure one guy is the one to get the 'kills' just to get a bit more of the experience for that person and get his/her kills higher and more accurate. On vanilla the average of soldier, scientist and technician skill levels gives you the enemy level, so try to strike a balance between rushing lots of combat and increasing soldiers ahead of the scientists and thus getting tougher enemies before you've researched good stuff... and letting too many missions go by and getting lots of tech, but not very good soldiers to fight the improved enemies with!
(EDIT: Oh, and BTW just incase you haven't tried it, paralyze does work on Rollers, actually on all organic targets. I've done it with pistols too, though it doesn't work enough times to be very useful with that. I'd stick with Cannon on Paralyze ammo if you do. It's higher chance of working, plus it always hits at least for some damage, thus always a chance of paralyzing.)
