Overwatch 2

This achievement does not require that you survive all 15 bonus rounds. Simply completing the initial 12 will award you the achievement during the match. I got the achievement with three random people in matchmaking with Zenyatta, Torb, Soldier, and McCree.
-McCree is the key here. High noon should be used on every elite spawn because it is devastating and recharges quickly. A great spot for this is the ramparts on the left to give a clear line of sight, but watch out for the hog's hook. The reason McCree is a must pick is for dealing with the Mercy wave. Provided Mercy has been discorded, a single high noon should take her out, kill all the misc. zomnics / any present shock-tires, and do massive damage to hog/junkenstein.
-Torb should place his turret on the perch near the door, and ult whenever an elite encounter spawns to deal damage and help with shock-tires. His ult builds quickly, so it's often better to waste it than to let it go unused. I've found his ult will be back at 100% by the end of a single hog encounter.
-Zen should use his ult only when absolutely necessary to keep someone alive (remember that every second your ult lasts is a second that you're not outputting damage). The priority here is using discord orb on important targets.
-Soldier should use his ult to clear shock-tires and ranged zomnics during tough spots when you feel overwhelmed. I find that using soldier to take out ranged zomnics quickly is a key to successful encounters because without their persistent damage the team can easily take out any elite encounter. Using his ult against a hog is basically worthless because it's not much better than standard shooting, and you can't score head-shots. His ult can also recharge quickly, so using it on Mercy, or Junkenstein can be helpful.
-Remember to eliminate shield generators! Deal with the Symmetra, then send one (and only one) person to destroy it. Ideally the soldier because he can sprint there and back, and can kill it quickly.
-Prioritize shock-tires first, then zomnics closing in on the door before anything else. You can survive one more second with a reaper or a hog standing nearby, but one of those get to the door and it's all over.

GENERAL TIPS

Characters Needed

Torb Zen McCree Solidier

Character Positioning

Soldier-Little Platform to the right watching the right door
McCree- Top Left stairs
Zen & Torb Middle Right in front of the door
Torbs Turret- On the middle bridge on the left side little stone closest to door

Characters Roles/PRIORITIES

Soldier-He is crucial to your success. His #1 focus should be RIPTIRES! His team mates should help him out but that's HIS job! There are not many tires so his real main focus is the zombadiers. His ULT should not be used on bosses as it doesn't really do much damage to them instead he should pop his ULT when it starts to get hectic with a lot of AI'S or AI'S getting real close to the door, that being said if all immediate threats are neutralized and has ULT remaining use it to help out with the boss.

ZEN-Discorb priorities, riptire #1, #2 bosses, #3 zobadiers, if there are no bosses or tiers zombadiers are priority #1. You should focus on healing Mcree mostly then torb second as soildier can self heal. Aside from that focus on killing the Zomnic's getthing close if none close then far zombadiers then zomnics. As far as your ULT goes use when needed but I have to caution that in prior runs using her ULT with a lot of AI'S near the door resulted in a loss because she could not get out of her ult fast enough.

Torb-He should focus on keeping his turret healthy ass is helps out a lot with thw AI's and to help build his ULT FAST! He should use his ULT for the really hard bosses such as ROADHOG & SYMMETRA. That being said besides that he is going to be the main reaper killer and should stay in the middle with in front of the door alongside Zen. You should throw all the armor down as you can right in the middle where you and Zen are but don't forget to neglect Mcree and soldier and throw them each a couple by their spots so they wont have to run down to get them.

McCree Keep the left door controlled call for help as needed use ULT ONLY for Bosses, and destroy shield Generators.(More on that later)

WHAT TO EXPECT/Round tips

Wave 1- Reaper | No need to ULT as a team kill the reaper.

Wave 2- x3 riptires

Wave 3- Roadhog, x1riptire |Torb should ULT the monster then McCree should to finish him off.

Wave 4- Junkrat, x1 riptire |McCree Should ULT if he doesn't die kill as team.

Wave 5- x2 reaper, x1 riptire |As a team kill the first reaper soldier can use his ULT on second one to help kill faster.

Wave 6- summoner, x3 riptires, x1 shield gen |At the start of this wave McCree should be standing where the reaper first appears before he teleports, destroy the shield gen then jump off and run down the bridge to the door Torb and Mcree can combo ULT the summoner.

Wave 7- x2 Roadhog |McCree should ULT the first one as a team kill him, soldier should ULT as needed to kill anything getting closeto the door (should happen around half way threw the round) and help on the monster if possible. Torb should use his ULT on the second Monster. (McCree needs to get his ULT for wave 8).

Wave 8- Mercy, Roadhog, Junkrat |Zen needs to orb mercy, Mcree then ULT'S her and should kill her, soldier should use his to kill the zombadiers and torb should ULT the monster.

Wave 9- x3 Reaper, x1 riptire | If soldiers gets ULT use on bots because it gets hectic as a team kill the first reaper, torb ULT the second one and Mcree the third.

Wave 10- x2 summoners, x2 shield gens, x3 riptires |McCree does the same thing as the first summoners round jumps down go to help at the door Torb should ULT the summoner as she gets to the bottom of the stairs soldiers should also pop ULT when he gets it as it gets hectic with AI'S around this time, when the second one appears and comes down Mcree goes up to get the shield gen then pop his ULT at the top by the gen.

Wave 11- x2 Roadhogs, x1 riptire |Torb should use his ULT on the first monster team shoot him till he dies McCree should use his ULT on the second one then quickly get his ULT back for wave 12 as it is crucial he has it at the start of the wave or within first 10 seconds

Wave 12- Mercy, Roadhog, Junkrat, x2 riptires | Zen needs to orb mercy so McCre can on shot kill her with his ULT, torb uses his ULT on the monster everyone help kill the monster and making sure no AI's hit the door getting to the end of the wave McCree should have built his ULT back to use on Dr Junkinstien.
