Description

Abyssal Trench is an underwater map that takes place under the sea. Since its addition to the game, this map has been remade several times. Abyssal Trench has the Scuba Gear modifier, which adds scuba helmets onto every enemy and bubble particles when an enemy dies.

Rewards

The game calculates how many Coins Coins, Gems Gem and you receive based on how many waves you survived and if you won a match. During periods of 100% more (Friday – Sunday), any earned is multiplied by 2x through the XP Boost modifier. The VIP gamepass also multiplies any earned by 1.25x through the VIP Boost modifier. These two boosts are additive. Regular boosts are multiplicative with other modifiers present on this map. Any rewards that end in a decimal point is rounded down, no matter the first figure of the leading decimal.

Strategy

The majority of the turns on this map takes place near the arch. Most ground towers should be located there. Therefore, ground towers should be placed on the first dune, where the path goes underneath the rocky arch. Cliff towers can be placed on the arch, meaning it is quite a valuable spot. They can also be placed on several mounds.

Patch history

On the first two versions of this map, on the top sail, there was a message saying "Rhythic was here", the creator of the map. On the first version of this map, there used to be five Robloxian figures spread around the map, including Rhythic at the wheel of the ship. There also used to be a SpongeBob SquarePants reference next to the main shipwreck, with a pineapple house next to what appears to be Patrick Star's house, in the first version of the map. Like many other maps that existed prior to the MEGA Update, this map was remade. However, unlike many other maps that were remade, Abyssal Trench retained a blocky style. The only changes were the aforementioned ones, the map being made darker and the path being slightly altered. In the current version of the map near the ship, Khompell's avatar can be seen. According to the Commander Aquaman Charm, the Aqua Commander skin is the defender of Abyssal Trench.
