Rocket League developer Psyonix has announced that it will introduce an underwater map to the game via a free update. The underwater map is called AquaDome.
The new map features visuals similar to that of BioShock Infinite, with a stadium surrounded by underwater sea life.
The new update will also introduce two new vehicles available for purchase via downloadable content packs, each costing €1.99.
Earlier this year the game's developer also introduced a basket ball map to the game and the new Rumble game mode.
The new update is expected to launch in October.
