NO!  IT'S MINE!  MINE,  I TELL YOU!

Today's a special event, a gold portal with the reward of 200 (!!!) total tokens if you clear all 3 difficulties.
Since the insane difficulty is what mostly everyone will have issues with, i decided to make a small reference point for those who want those 100 reds.
Below are the 4 mechs you will encounter in this portal, 2 buggies, 2 tanks, 3 mechs, and Roaster.

150~ Cooling  / 150~ Regen on buggies.
200~ Cooling / 200~ Regen on tanks.
250~ Cooling / 250~ Regen on the mechs.
275~ Cooling / 250~ Regen on the boss.
Here is the mech that i used to clear insane, without a revive: 
                   
Here's a more free to play version that should work just as fine: 


You could also use a boiler, or a physical mech to brute force with damage, but i prefer energy more for these portals as it disables their weapons.
Good luck!

Abomination is kind of like the heat version of terror cry.

Claw requires a different setup because it's fixed.  I have Claw but don't use it for that reason, because I prefer mobility without having to use all the moving items (teleporter, charge engine, grappling hook) all the time.  But the HP of Claw is huge, nd you see a lot of successful players with it. 
 
But if you go for Claw then in my opinion you have to have Nemo, because Tonto is limited to range 2-4 and that goes badly with Claw's immobility.
 
My physical mech has Tonto and Massive Stone Feet, and it's going OK, although I'm thinking about replacing it with the backfire physical drone. - whichever one of the Protector drones that is (don't have one just now). 

From recollection, you might be a little short - but those final stages take days each, so you can be grinding the gold while the HQ is upgrading, so you might be OK at that.  Go for it, I say.

I suppose if you want to try for legendaries at the top end of the factories while also producing commons and power kits, you'll need minimum one maxed factory, one at 15 and one just level 1 - which is what I have, in fact.  But I don't try the legendaries option much, as it's so expensive for the low chance of legendary when you can be getting epics as a bonus quite frequently when collecting commons. (nice feature, that)  Main thing for swift progress is HQ at max, one factory at 15 and another not upgraded for commons, plus all four gold mines maxed.  
But Spam's right if your ultimate aim is everything maxed - it'll be slow and frustrating later on if you find you need to max up something you could have done earlier. (I may end up cursing and grumbling if I ever need to upgrade my factories further)

My tips would be:
Two factories is as many as you need for now. 
Only upgrade one factory for now, because regular commons from a level 1 factory are so cheap at the moment.
Max up the number of gold mines (four eventually) before ading any more factories. 
Early on when everything upgrades fairly quickly, take the base as far as you can before you have to wait more than an hour, then upgrade the gold mines as far as they'll go, then upgrade your "best" factory as far as it will go, then upgrade the base some more, and so on.

Aaaaaagggghhhhh!!!!  Bad memory.  I was a noob, I knew no better, but the pain still lingers.

P.S.  When I said "base" in my reply, I meant "HQ".  Apologies for any confusion.

As the FAQ says, we do not manually recover accounts.
 
Especially not for people claiming accounts that we know for a fact aren’t their own. Please cease this.

Is there any way of merging these endless repeated topics abut the base into one so they' don't clog up the forum so much?

From my experience, the percentage per/mech is like how much you did to that guy, you need to take the lowest damage while also killing their mechs so its hard to get 100%. You clan score(red arrows) is the sum of how much your clan did to the other clan.(again its only my experience)

What you have is base, which is the alternative to silver boxes. If you want to disable your base, use the following link: https://community.supermechs.com/knowledgebase/disable-base-request/?do=form&d=2.
Three things to keep in mind:
1. Disabling base isn't instant. Be patient.
2. Base is superior to silver boxes once maxed.
3. You can only disable base once, regardless of how many accounts you have.

Well, the developers do not have much time to disable the bases of the players, which does not always even reach your turn, simply because about 40 more players have thrown an application, and the developers were too lazy for all the players to disable the bases. If you really don’t like the base, just send a request there https://community.supermechs.com/knowledgebase/disable-base-request/?do=form&d=2 and do not ruin the mood of other people with your "Please turn off the base."
