Expert Mode has been confirmed to be undergoing a rework, and all content here is subject to change. No information from it's Rework should be added on this page, Information about it should be added to the Unreleased/Scrapped Content page.
Description[]
Expert Mode is currently the second hardest mode out of the five available gamemodes. It consists of almost every single enemy from every previous mode, with Armored Runners and Eradicator MK II being the only enemies exclusive to this mode and Endless Mode. This mode features multiple stealthed enemies past Wave 17, with the minibosses (3 Predators) being stealthed, and Eradicator MK II, the boss of Expert Mode, being able to stealth themselves for a short period of time. Completing Expert Mode is an impressive feat, and is a great way for endgame players to grind for 
and XP. This mode will award you the That Was an Explosive Event! achievement, which can be claimed to award the Defeat ERADICATOR MK II badge.
Tips[]
- Assuming you have joined the group, you should have enough money to place down a Laser Gunner, Golden Ranger, or Toxicnator, all of which should be able to handle the early waves by itself.
- Stealth enemies will appear at Wave 17, which should give you more than enough time to prepare for them.
- Due to the positioning of Grenadiers and Elite Grenadiers often being after or between tanky enemies and large hordes, setting towers to Last or Weakest is beneficial in some cases.
- It is highly recommended that you get the Laser Gunner to 2-0 first in quads before getting 2-2 as bullet resistant enemies arrive at wave 7, and will likely be a problem for you if you don't have a teammate with an Armored Factory or Artillery placed down.
- Many enemies in Expert Mode have stealth and bullet resistance, and tend to be clumped up, so using explosive towers like Artillery is highly recommended.
- Top Path Artilleries can be very useful due to their splash and high damage output which can help save runs from Elite Grenadiers and their spawns, however a lot of the enemies are stealthed so it is recommended to have a X-4/X-5 Sniper or X-5 Laser Gunner to help reveal the stealthed enemies due to the 5-X Artillery having no stealth detection.
- Warship is better suited for Expert Mode due to its ability to completely clear hordes of enemies due to its massive explosion radius and damage output. It also has stealth detection and a great single target damage as well as the capability to remove stealth map-wide for twenty seconds in its Bottom Path, although it is very costly.
- Make sure to place Farms to make money, as although it is possible for at least 2 players not to farm, the wave bonuses do not give much, and it is almost possible to not have enough money for sufficient defenses because of them.
- Additionally, enemies in the later waves start to not give cash, making Farms even more essential.
- Use Juggernaut, John, and EDJ for high DPS against Eradicator MK II. Missile Trooper's Javelin upgrade will be less effective as the boss takes 30% less damage from explosions and the tower doesn't have much health to begin with.
- Railgunners are also an effective way to deal with Eradicator MK II, especially with the bottom path, due to its high damage output, health, and range. If paired with John, groups of bottom path Railgunners will decimate Eradicator MK II.
- Artillery is an incredibly useful tower for Expert Mode, as it can deal massive chip damage to tanky enemies like Revived Abominations, take care of the giant hordes, and easily target Grenadiers and Elite Grenadiers.
- However, it is recommended to sell it on Wave 40 as it will not do much to Eradicator MK II due to its 30% explosion resistance.
- Laser Gunner, Sniper, Juggernaut, and Railgunner are a necessity on Expert Mode due to some enemies having both Bullet and Explosive Resistance, which only Laser Gunner (from 2-X), Sniper (from 4-X and X-5 only), Juggernaut (from 4-X) and Railgunner (any level) can damage.
- When Eradicator MK II isn't attacking, spam cheap towers like John and Operator as bait to prevent stronger towers from dying once his assault begins. Sell towers that have low health or are losing too much health from incoming attacks. It is also recommended to use stealth revealing towers such as X-5 Laser Gunner, Warship, or Sniper if you have other towers that do not see stealth enemies.
