Plants vs. Zombies Garden Warfare 2

Solo Method

Mode: Solo Ops
Side: Zombies
Map: Colizeum
Character: Super Brainz (I just used the basic, but the others should be fine if not better.)
Area: Middle of the Colosseum
Make your three other teammates 2 Super Brainz and 1 Scientist. (I used all basic Super Brainz and a Marine Biologist, for the people who are curious.)
Always fill near areas with long range turrets, keep one healing (Dr. Heals) near the center. I only used Gatling and Rocket Bots, so this method won't require grinding for money, just basic Bots worked.

That's all it took for me on the first try but I can imagine there is a bit of luck for the bosses. The bosses I rolled were actually quite hard so I do believe it is still possible with all bosses.

Tips:
Make sure to switch characters before you die, you cannot switch when you are waiting to revive.
Make sure to do the extra challenges.
Keep in mind, you take damage when using the tornado move (Turbo Twister).
Make reviving a priority, the only one who should die somewhat often will be the scientist. (For me, he went down around three times.)
Remember that you can attack while reviving, just don't use special abilities.
Be sure to use Super Brainz' beam the majority of the time.
To make quick distance, jump as high as you can and use the Heroic Kick.

Do this and you should have no trouble, until a possible update.
If you have any questions just let me know.

I have a super easy method for this.

I took some of the information from the other guides and used it here. The only thing I really changed was the characters joining you.

1. Pick graveyard ops (I chose electro brainz as my character but it's up to you).

2. Choose the map colizeum.

3. Choose 3 marine biologists as your allies. (Or equivalent if you don't have him)

I wouldn't recommend palaeontologist cause he has been pretty consistently useless whenever I have used him.

4. Build a Dr Healz and loads of rocket and Gatling turrets.

You shouldn't run into many problems, the only time I did was during super boss waves. The way around this is to switch to a marine biologist and make sure you are healing and reviving while the A.I mops up.

This was my first achievement guide, I hope it was ok. Feel free to give me some notes and feel free to message if you have any questions.

First of all i did this in garden ops as i prefer plants to the zombies, now to start, load the game up when it has loaded you will want to go the the plant side side of backyard battleground from there go to RV to start garden ops then press click onto create multiplayer match, once it has created the session i found that zen peak was the easiest map to do this on set difficulty to crazy and set permission to open, I did this with friends and one random but this should be achievable with 3 random people, click ready now i did this with two sunflowers and two roses but peashooters are equally as effective as roses once you have selected your character head over to plant B now you have 30 seconds until the wave starts so you will want to grow some basic plants for the first couple of waves but as you progress you will want to plant some healing plants and more of the effective plants, now aslong as the sunflowers do there job of healing and roses/peashooters do there job of getting the majority of the killls you should be fine. waves 5 and 10 are the only potentially difficult waves depending on the luck of the spin, when i did this i got lucky and didnt have any difficult opponents from the spins, if you do get a super wave for example you will want to plant some extra healing plants focus on crowd control like weeds and once you have taken as many as possible out focus on the boss work as a team use your special abilites providing everything has gone smoothly you will have completed all ten waves. i cannot confirm that if you die when escaping you will void the achievement so again work as a team and should all be fine for those that have played the first game this is much easier in comparision upon escaping you will unlock the achievement.

To sumarise
:Zen Peaks
:Zone B
:Two sunflowers
:Two of your own preference
:Teamwork
:constantly grow plants



Edit: I should mention that the sunflower i was using was a power flower and not the basic one two roses were the basic flowers though

Here is a tip in case you burn through your self revives and can't get back in to round.
Quit out of the game and re-join on one of the people still in game. You'll spawn back alive and can help finish the round.

If multiple people are out of action, do it one at a time so that the round keeps playing.

Not really a "solution" so to speak, but if anyone was wondering, yes, you can join in the middle of a game in progress with randoms (or anyone, I suppose) and still get the achievement. That's how I just got it. I jumped into a random match on Craaazy in the middle of Wave 4 and it popped after we escaped in the RV.

After countless attempts with SuperBrains/Scientists on several maps, I finally did it yesterday with the plants. I never got further than wave 8 before, but with the following setup I managed it on the first try, even though wave 10 was a super boss wave.

Mode: Solo Ops
Side: Plants
Map: Colizeum (in the middle)
Character: 4x Sunflower (I used Vampire Flower)

Pro:
- Anyone can quickly revive
- Massiv heal
- Self heal by vampire ability
- Sunflowers have more power than scientists, especially at long range

I personally would try to get this by searching for a Crazy difficulty ops game and doing it with multiple people, I did this on Garden Warfare 1 and easily got it.
