About this game

A 3D co-op submarine simulator with up to 4 players, where you fight for control below the Antarctic. Taking place in flooded caverns deep below, you and your CREW will be tasked with operating a submarine to eliminate outposts, and defend against waves of enemies. Your vessel is specialty built using the latest in material science, to withstand the unique conditions posed by this new environment

Unlock new interesting torpedo types, and deploy them in combat. Load them immediately, or store them for future use. Planning and forethought are essential to a decisive victory against all enemies in the frontier

Good coordination and communication are heavily rewarded. Work together with friends to operate your vessel smoothly. Form a command structure, or naturally fill in where needed. Ensure steady operation of your submarine, and dominate the enemy

- In depth sonar & hydrophone mechanics. Listen for your enemies, and bounce sonar pings off walls to gain advanced vision of the caverns
- Craft unique torpedo types, for different situations
- Forethought and communication are heavily rewarded. Pick your engagements wisely
