Beating last mission on extreme difficulty

[ANZ]

I'm not too good with english, so I decided not to making it into real guide.

Invincible turrets make it look like there are no reason to attack enemy spawners. But it's just the best way to win. When you take them all, mission will be finished immediately. Cargo unit won't even spawn.
Try and hone this tactic on normal difficulty at first.

Chose "SQD will heal slowly when it's not moving" module. It will turn SQD-96 unit in almost invincible "turret".
After starting, quickly capture all 3 spawners by SQD, and left him near third (highest) one, to defend this path.
At the same time you should appoint arriving point from first two spawners to Scouts transformator, and defending this area from bombs units.
Next, you should wait till there'll be no less than 50 scouts ready.
Before it's ready, you could make some optimizations in unit positions:
Capture Freeze point;
Left some units on third spawn and make new ones move to Venoms transformator;
Put Venoms on enemy coming paths;
And so on.

When scouts are ready, move them to Gunner and Medic transformators on the top of the map. Turn 2/3 into Gunners and 1/3 into Medics. Immediately move them back to safe area.
Beware Bombs!

Next, slowly move this Gunners and Medics with new Scouts support to Crabs transformator at starting locations. Turn Scouts into Crabs and move this little army upwards to fully block this path for enemies.

Wait for enough Scouts to appear and repeat Gunners / Medics transformation. But don't move them from here now. Defend this area. It's also good to move Crabs here.

If you did everything correctly, enemy can't destroy you from now on!

Now you only need to wait for another Scouts pack, and move them to capture top right spawners. Attack from above. Use Freeze on two turrets and capture first spawner between them, and then second one there.

Just repeat all this moves to take other enemy spawners.

I'll try, but no guarantees that I could do it again. It was on the verge of failing. One moment I even lost first spawn and was close to losing second one, but I managed to take it back.
Every few minutes game makes autosaves of the match. If you feel that you screwed up, just load that one save where all still was ok.

No video are coming. I've uninstalled the game after beating it on 100%. And now, after I ran it again, I found that all my progress are gone. It happened because save files are located in game directory I don't using cloud saving too.
It shouldn't be too hard to beat this mission on normal with my tactic. Where you had a problem?

Thanks. It works well. First run on normal was successful, and then one try and I've beat the extreme.

Thanks, your tactic works. It has been a while but i managed to beat this mission and as well doing full video of this mission:

The only thing that i can add is that venoms must be stading on path not too far from first spawn place and supported as well by same units.

Interpreting the general strategy:
Scouts are fastest and decent at fighting basic/gunner. Turrets protecting enemy spawns are invinciblelame. Freeze two turrets, take over the spawns, and prevent enemy units from recapturing by blocking with medics, claw, and gunner or venom. Bombers will harass you ON BOTH SIDES throughout so you need SQD or venom/gunner and medics to block them.

Just my take on it
SQD takes spawn#1,
Spawn#1 to scout & SQD kills neutral scouts,
SQD to spawn#2,
Spawn#2 to scout,
Scouts to Spawn#3, good rally point BLOCK BOMBERS with venom or SQD
SQD to spawn#3,
Spawn#3 to venom,
SQD to spawn#1 to block bombers, get freeze with SQD or scout.
SQD to claw,
Spawn#1 to claw - they protect your venom from gunners/basic units,
Claw & venom to block left bombers, YOU NEED MEDICS now
SQD back to venom and leave it here,
All scouts to medic/gunner, 2/3 gunner 1/3 medic roughly,
Complete the left side block with gunners/medics,
Spawn#1 to scouts since you don't need claws if you're not losing units on left,
~50 scouts to capture a set of enemy spawns starting top-right.
Freeze two turrets and send in the scouts to take spawns.
Block the middle from retaking by moving SQD to middle,
Spawn#3 to Gunner/Medics. Venom no longer necessary
Wait for ~30 scouts and freeze for middle,
Left side, move everything except venom up to the top to stop recapture,
Take the middle by freezing turrets and scouts to spawn,
Send everything left to left side spawnif you don't want to wait for freeze,
Don't forget the small spawn by the turret.

Now it's your turn to do it in-game. If bombers take spawn#1 early just restart took a few tries and 40minutes. Make sure your MEDICS are behind your venom/claws.
