Excuse me? When the invasion starts they literally become the front line, regular army of whole Earth, they have Air Forces, Ground forces, Heavy armor, Drones, Fleet (abridged version) and Orbital defense. If this is not a definition of regular army then I dont know what is. There is no dispute in use of such weapons when the invasion starts, especially in defense missions.
First of all, you are grossly overestimating X-Com's firepower. 5 planes don't make air forces. 100 men don't make a ground army.
Officially, X-Com is something like glorified FBI, with access to military equipment. This does not make them an army; if nothing else, they're about 1000 times too small. And the Council would never, ever agree to give them more military rights, even the factions which support X-Com.
In practice, X-Com is a special forces unit at best, with some auxiliary stuff like fighter planes.
Still, this is not really on topic. Your question was about adding some heavy guns to the game. And to this I would say, yes, possible, if they're not too broken.
Well you could refine all the MAGMA trash in something more usable, plus slap the "the further the target, the harder it gets krumped" trait.
I don't really know what to say to an argument that M.A.G.M.A. weapons are trash when in my opinion they're uniformly best out of almost all firearms in the mod (with some exceptions like the Arasaka 3000).
But having said that, I have just overhauled M.A.G.M.A. pulse weapons this week. Further changes are possible, I am considering some reshuffling of their guns availability (pulse weapons earlier, something like the Auto-Cannon later, etc.).
Is that your way of saying: "I dont wanna do it!"?
Maybe a litte, yes
But primarily, I don't think they're done badly as they are. The mod has seen several incarnations of these weapons already and since I settled on this one, then I consider it best.
It's very hard to do miniguns justice while not making them too broken.
Large weight, takes a lot of space in inventory, tiny clip size, inaccurate. Totally covered. Also pulse guns are too late in game to compete with anything. The only gun from MAGMA I really love is Thrasher with alloy ammo, that thing just rips everything.
Agreed, see my comment above on the pulse weapons. Also I added new clips for them, which should make them more attractive.
Guess aliens suck at tech as much as earthlings do.
Sort of; if anything, they lack good soldiers, due to how their society works (maximum stunting of personal development and accruing experience). Therefore their idea is to think of their troops as biological robots with as good raw physical stats as possible and armed with weapons optimized for idiots. (There are exceptions and other variables of course, I'm generalizing here.) So a standard issue alien weapon is supposed to be easy to operate and allow obliteration of enemy with sheer brute force.
How about more sensor grenades, maybe slap a IFF on top of that? Cause the only "mines" we have are basic grenades.
I can add E-115 proximity grenades, no problem. It's just that very few people use this kind of stuff, so I kinda never remember.
Also why not make a Incinerator grenade? Like we have an alien flamethrower, we can make a very strong incendiary grenade base on tech we get from this flamethrower\Incinerator.
We could. I'll add it to the to-do list, too.
Also what stops you from strapping a 40mm autogun on Juggernaut exo? Abandon reason, know only war!
My day job...
I can think of something.
