Pyramid of Doom is a mini-game in Plants vs. Zombies 2 that’s unlocked once you’ve completed Day 11 of Ancient Egypt. It’s an endless-mode type of mini-game that starts you out with three plants – Sunflower, Peashooter and Wall-nut – and 5 lawn mowers. At each level, you are allowed to choose 1 of 3 random cards to add to your collection. Sometimes, you can also get a lawn mower (to replace any you’ve lost), plant food or a chockfull of Sun. Any left-over plant food is carried over to the next level.
So how do you conquer it?
At levels below 10, just apply any strategy that you found useful throughout Ancient Egypt. Here are a few tips:
Plant at least one row of Sunflower, using Potato Mine to stop the early zombies.
Pick low cost, high damage plants like Kernel-pult, Snowpea and Snapdragon when their cards come up.
Use Wall-nuts to block zombies while your low level plants bombard them.
Use Grave Busters to get rid of those pesky tombstones.
From levels 11-20, keep building up your arsenal and collect the following plants as soon as their cards come up:
Bloomerang – Hits up to 3 targets in their lane, twice. This is especially useful in levels with a LOT of tombstones.
Snapdragon – Breathes fire that causes damage in 6 adjacent tiles. A whole row of Snapdragons is awesome to behold, and pretty much stops most zombies before they get a chance to start munching.
Grave Buster – Consume graves they’re planted on. Yeah, you really really need this.
Twin Sunflower – Gives twice as much sun as a normal Sunflower. When the going gets rough, one sun is not enough.
Winter Melon – In the game Plants vs. Zombies winter melon can do heavy damage to nearby zombies and slows them. This has got to be the plant with the highest damage output and will be your main weapon in the later stages.
Additionally, here are two Premium plants which I think are absolutely needed for the higher levels (If anyone can come up with a strategy that doesn’t use these two plants, then hats off to you!):
Imitater – Lets you use two of the same plant during a level. Extremely important for building up sun quickly enough to beat the first zombies in the higher levels.
Power Lily – Creates one plant food out of thin air. This plant becomes very important after level 20, when zombies only drop 0-2 plant food per level.
You can start using the strategy below as soon as you get the needed plants, substituting similar ones as needed. For example, in the earlier stages you can use Melon-pults instead of Winter Melons.
So here’s the winning strategy…
Step 1: Choose your plants and build up your dragons.
The ideal line-up is: Twin Sunflower, Imitater (for a second Twin Sunflower), Wall Nut, Grave Buster, Snapdragon, Bloomerang, Power Lily and Winter Melon.
Plant a Twin Sunflower on the second column and use all your plant food on it to build up sun quickly.
Plant a second sunflower as soon as possible. The objective is to build two columns of sunflowers as soon as possible.
As soon as the Grave Buster is ready, start clearing tombstones.
Place a Snapdragon on the second or fourth lane of the middle column, depending on where the first zombie appears. The objective is to fill the whole column with ‘dragons.
If you have enough sun for a Winter Melon, place one on the first column in the lane where it’s needed most.
Your vulnerable lanes will be 1 and 5 so beef it up with a Wall-nut in column 6, and/or a Bloomerang in column 4.
Step 2: Make plant food!
This is something you need to keep doing as soon as Power Lily is refreshed.
Use the plant food to boost your sun production if needed, but try and make sure that your plant food bar is full by the end of the level, in preparation for next level.
Note that Power Lily recharges slowly, so there will be levels where you won’t get enough to time to fill up on plant food. If this happens, use your coins! That’s what they’re there for!
Step 3: Build up firepower.
Plant a row of Bloomerangs behind the Snapdragons.
Complete the first column of Winter Melons.
Once that’s done, start building up sun again and replace the Twin Sunflowers in column 2 with Winter Melons.
At this point, you’ll notice that your keeping the zombies at bay and that your Snapdragons are barely getting any action. Time to start replacing them with more Winter Melons.
Step 4: Win!
