"Explore Megapolis's deepest point: the ocean trench. Get there first and you'll earn a reward!"

Oceanic Trench is a Timed Quest in which the player has 192 hours to build and upgrade a total of 7 new fixed structures with assets leading to exclusive rewards. It was released as part of an update on Fri August 21, 2015.[1] This quest introduces a new expansion zone named Archipelago.

If someone completes the quest steps after the timer run outs, they still get Experience sm, Coin sm and asset rewards. Although they don't receive the Rain Hotel and Challenger Bathyscaphe.

"Megapolis's scientists have found a mysterious trench in the ocean. According to the oceanologists, it could be the deepest trench on the planet!"
"The residents are asking the mayor to: explore the trench in the ocean"
"Start researching the oceanic trench — build the Oceanic Station, the Sea Zoo, the Coral Lighthouse and the Bathyscaphe Production Center. Be the first to explore the deepest point in Megapolis and get a reward!"
