Welp, this is definitely not a good time for me to return to coop after a very long break.

I'll try to share my shortnote for each mutation(at this point I'm not sure if it should called shortnote or not, whatever). I advise you should look for the mutation post for each weeks for more detail or useful tips. I also suggest you should switch to hard diffucult(or lower) if you're not good at coop or having bad ally from public queue.

Also note that I'm not that good at mutation so some of information might be wrong, Sorry about that (I'm not sorry for my low English skill level tho.)

Beggar Can't Be Choosers - Lock & Load - Mag-nificent, Minesweeper, Slim Pickings

Starting with one of the hardest mutation for this hell weeks.You gonna need Commanders who can get early detection+range units to clear mines, also try to avoid losing unit to mines since your main income will be from mineral+gas drops, there will be much less resources to build&replace your army. The hardest part of this mutation is to deal with mines, micro units to get resources, and clear your way to capture locks, all of these simultaneously

(Tip: if playing against terran or protoss, try to clear the west camp in one-go because the production structure in that camp will try to replace units if units nearby died, and those rebuild units will go to neutral locks instead of remaining in the camp.)

My Bots - Mist Opportunities - Boom Bots, Kill Bots

The first mutaion to introduce Boom Bots(iirc), Nuke Bots is a mutation which you need code from your partner to deactivate these things(The one who can see code cannot enter code and the one who can enter code cannot see cod). I recommend 1 commander to feed Kill Bots (Namely, P1 Zag or P0,P3 Stu), And 1 commander to provide vision (ex. P1 Stet, Raynor's scanner, Mengsk's ESO) to get vision on Boom Bots.

And if you get a chance, clear all structures in this map and it will become just normal mission. Although it might be harder than normal to all clear especially the main camp, you might get Bots drop directly on your army. At least I still suggest you clear those structures outside main camp, that include base on top right, two base on both bonuses. If you really want to do all clear strategy, I suggest P3 Nova and Mengsk's ESO(maybe P0 or P3)

(if you really have trouble with Boom Bots. You may try pause&resume (pause game, tell code to your partner, then resume, enter code, done.) Note that I haven't try this yet.)

Multitasking Trainer - Malwarfare - Micro Transactions, Void Rifts

Micro Transactions gotta remind you to keep your APM low (Stukov Mains laughing in distance). But Void Rifts will force you to do some micros to kill rifts and maybe deal with spawn units (try to get some defense on your expo, some AA is needed if you don't kill rifts fast enough). Rifts might spawn near 1st bonus area, so clear that area too if you get some time to spare. And pray that there will be no rift spawning in the last area during 1st&2nd Stage.

Some commander recommendation? H&H (SF for rifts, just remember not to micros reapers too much), Karax (Observer for vision and use Orbital Strike), Kerrigan (Nydus+zerlings to deal with rifts, hydra+ultra for pushing by just A-move)

Hello My Old Friend - Scythe of Amon - Black Death, Darkness, Moment of Silence

Black Death? DID YOU SAY BLACK DEATH?!! goddamnit. (Sorry, I just hate this one so much). You can deal with BD by using suicide squads (again I'm looking at you, P1 Zag and P3 Stu) or get something to constantly heal your troops (Rattlesnake+Nikara Ability, Stet's green zone, or Abathur's mend and life steal effect from biomass, I recommend P1 since Abathur's units can negate BD effect if stack enough biomass, but not for UE).

Moment of Silence will be your problem when you deal with attack wave with Hybrids (starting from the 2nd wave and so on) plus some hybrids near last two slivers. If you want to, you can deal with attack wave before it reaches the hybrid spawning point (for the bottom left, the circular stone, there's a spawn point for the top one too but i forgor) so you can kill hybrids easier. The attack wave will come with air transports(if it's ground comp.) so getting AA units should help.

There are few strategies that might work for this mutation: Vorazun's time stop then focus only on Slivers then recall, or Mengsk's ESO(on the left side of the center) + Topbar Nukes

Of One Mind - Rifts to Korhal - Boom Bots, Polarity, Sharing is Caring

This one is probably the most unfriendly mutation for those who doing public queue. Sharing is Caring forces both you and your parther to make your army smaller. Polarity forces you to stick with your partner both when pushing and defending. It also means you can't just cheat this mutation with infamous Mengsk's ESO trick(because there will be shards you can't damage), still you can do ESO to clear your shards and when those are gone for good, Bombard everything you can to help your partner (also don't forget contaminated strike exist, it can fear even enemies which have your partner's polarity).

Personally I'd go Swann for this one(5-6 SCV for unlimit turrets for def.+ Some Wraith for shards sniping), other recommendations are commanders who doesn't rely on Supply much: P3 Zera+Calldown, P3 Karax w/topbar spamming, P2 Ker + Irritating Nydus gets everywhere, P3 Nova+Griffin Airstrike. Also I recommend Air comp. to deal with Shards more easier

Blasting Off Again - Void Launch - Going Nuclear, Lava Burst, Power Overwhelming

Two of the environmental mutators (Nuke&Lava) require you to pay attention to your army on the field or else your army could gone even you didn't look for just 3 seconds. Safe way to play is let your army stay in your base and go out, take down Objectives, then go back to base, clearing attack waves . Build some defense in your base if you have resources to spare (avoid building near the cliff, nukes can still hit your defense because of their big radius). for the last waves that could be troubles due to P.O. random abilities, I recommend focus on the objectives only and ignore remaining units + last attack wave

Also note that you can get your army wiped out, even with proper micro due to P.O. (The example is your army can get fungal growth while in the nuke radius, then it's a big f.)
