How to Pass the Research Institute in Plants vs. Zombies 3: A Guide to Clearing the Research Institute

There are many levels in Plants vs. Zombies 3, and how to pass the Plants vs. Zombies 3 Research Institute? To quickly get through this zombie-filled area, players can first check out some guides before making preparations. Because relying solely on your experience or effort will take a lot of time, it's better to preview it directly in advance, so you can aim to clear it in one go.

1. Plant Recommendations

Before attacking, everyone can first prepare some useful plants. The first recommendation is to use the Pulse Peach. Using it can evolve some plants into electric types, which then have the ability to paralyze. Since three electromagnetic emitters will appear at the top of the map in this level, causing paralysis and additional damage to non-electric type plants, you must bring electric type plants.

In addition, there is an effect of enhancing current supply. As long as the plants are connected in series, they can gain a huge attack speed bonus and cause bullets to split, thus dealing higher damage. Then, place electric type plants in areas with electromagnetic emitters, ensuring that other plants do not suffer extra damage.

2. Specific Strategies

After passing the first level, mechanical tombstones will appear in the second level, with a large number of tombstones appearing from the sky, which need to be destroyed within a specified time. Here, you'll need to use the Electric Currant, which can quickly break the tombstones. Pairing it with Puff-shroom can create an electric output effect, increasing the efficiency of the output.

In the third level, you can obtain the Pinecone Shooter. Place it on the field because it can penetrate firewalls, helping you pass the level effectively! In the fourth level, switch to the Electric Mint, which can turn Wall-nuts into Holo-nuts; not only can they easily withstand zombies, but the output efficiency of other plants is also high.

In the fifth level, plant the Cactus first, as there are many drones here. Pairing it with the Pinecone Shooter can help you pass the level easily. After passing the level, you can unlock the Garden System, where you can grow the plants you need. However, low-flying drones will appear in the fifth level, which will destroy plants, so you cannot place plants where they appear.

When you reach the seventh level, continue using a row of Pinecone Shooters and a row of Cacti, paired with some props, to make it easier to pass. In the final level, Mechanical Shark Zombies will appear, sneaking up from underground, so you need to use electric attacks to hit them. By planting more Cacti, you can use them as cannon fodder, gradually wearing down the zombies to pass the level.

If you want to explore more map levels, it's best to study how to pass the Plants vs. Zombies 3 Research Institute first. The Research Institute is a very unique level, incorporating new mechanisms and gameplay. You cannot use your usual habits or combat methods; after using these techniques or plants, you can naturally pass the level quickly.
