Description

The Mortar is an advanced cliff tower with a long range capable of damaging enemies with its explosions. It can be unlocked by reaching or purchased via a gamepass for 395 Robux. When the player reaches, the Mortar can be claimed by using the pop-up message that appears when joining the lobby. The Mortar is a cliff tower that shoots rather slowly but deals high damage over a large explosion radius. It has a long range, but as the Mortar shoots at a target farther away, the shells take longer to reach their target. These shells will generally land behind the targeted enemy. The explosion it produces is separated into two spheres; enemies in the inner sphere will be dealt 100% of the stated damage, while the damage in the outer sphere decreases linearly. At Level 4, when the Mortar's shells explode, they will drop three cluster bombs, which will create additional explosions when they hit the ground. These will land around the main explosion, meaning they are very unlikely to all hit and deal full damage to the targeted enemy. By default, the Mortar can damage Lead, as well as target all non-hidden flying enemies. The Mortar is immune to all stuns by default. The Mortar is considered an all-round tower due to its relatively cheap placement cost, expensive upgrade prices, and its ability to effectively handle groups of enemies throughout the game thanks to its high area damage and strong overall damage output. The Mortar has a placement limit of four per player. This is increased to five in PVP mode.

Strategy

The Mortar is essentially a cliff-based Rocketeer. However, the Mortar deals less single target damage without its cluster bombs (which are very unlikely to all deal full damage to the enemy) while having a significantly larger explosion. This makes the Mortar a better option against hordes. In most cases, the Mortar's shells will land behind an enemy. This can be useful for hordes of enemies, as the Mortar's shells will land closer to the middle of the hordes instead of landing at the front. This allows its explosions to hit more enemies. However, this makes the Mortar somewhat weaker against single targets. As explosions will land behind an enemy, the enemy will be further away from the center of the explosion, which can reduce the amount of damage it receives. This is usually negligible for slow enemies, but for much faster ones like the Fallen Rusher, the Mortar's DPS may be reduced drastically. At Level 4, the Mortar's shells drop cluster bombs when they explode. These cluster bombs will also explode when they hit the ground. However, do note that these should not be relied on, as the cluster bombs are very inaccurate and create a smaller explosion than the shells. At least 1 or 2 Level 5 Mortars can be efficient with taking out hordes of Breaker4s due to it being able to kill it in a single hit and its cluster bombs killing the Breaker3s that spawn. Compared to the Ranger and Sniper, the Mortar has a significantly smaller range, lacking in range when cliff spots are far enough from the path. The DJ Booth can aid with this by boosting its range.

Patch history

Outside of sales, the Mortar is a tower with a gamepass cost of 395 Robux, lower in Robux compared to the Turret which is a tower with a gamepass cost of 450 Robux. The Mortar is loosely based on the Mortar from Tower Battles and the Mortar Monkey from the Bloons Tower Defense series. When the Mortar was first released, it would have been affected by shockwaves created by bosses from their Stomp abilities. This would later be fixed the same day. This glitch would later return in the Overhaul Update, though it only applied to the Grave Digger's Stomp. This was later fixed in the Entity System Update. The Mortar formerly shared its Level 4 icon with the Ace Pilot's Level 2 icon, but rotated. The Mortar has a unique explosion at Level 5. It will create a nuclear explosion, instead of the usual explosion most other splash towers use. Unlike the game, dropping a shell in real life will spontaneously fire the mortar. In the game, Mortar drops in a shell after firing and waits for an enemy to come close to fire again. The Mortar's default skin in the lobby uses its Hardcore Testing BETA appearance with its face changed, instead of its current appearance.
