Aquaman

Aquaman is an event that started on November 20, 2018, and will end on January 2, 2019. It is sponsored by the upcoming DC movie Aquaman.

Aquaman: City of Rolantis
Some players reported that the hubworld was pretty laggy, with choppy swimming animation and being unable to attack.

Bandit Simulator
Bandit Simulator was criticized for its tedious and time-consuming quests, particularly the pearl stealing objective. There would only be one cyan-and-yellow chest in the treasury at a time, only rewarding the player with one pearl. Following a raid, the building would close for 5 minutes. Sheriffs would also camp inside the building to either disarm the bomb and close the building, or kill bandits trying to enter. Many players sped up the process by server-hopping or by rejoining the same server each time they robbed the pearls while the treasury was open (if they had Roblox+ to view specific server pages). Whether a glitch or not, players who already had 50 kills before the event began also couldn't receive the Water Dragon Head.

Trivia

 * This is the first event to have an Rthro package as a prize.
 * It is the second DC Comics event after Teen Titans Go! and the first of the extended universe of DC Comics.
 * The objective for the Aquaman Backpack used to be to collect 20 pearls instead of 30. There also used to be a second pearl chest in the treasury and another one in the church. It is unknown why this change was made, although most speculate that it was to increase the difficulty.
