Knights of the Deep
Steam
Knights of the Deep is an action-packed, online fighting game with crustaceans. Battle against your friends in free for all or challenge other players in a team-based match using a variety of items and special abilities. Master each crustacean's unique fighting style and climb the hierarchy!


Each crustacean has a unique playstyle, master them all and dominate the battlefield!

Claw, jump, slice, and parry your way through your rivals using a variety of special moves, split-second dodges and well-timed counter attacks.

There are items and power-ups spread all over the map, learn how to use them at the right time and change the tide of battle! Fight with guns, swords, hammers, bombs and magical staffs... or just play the mighty Fanfare!

You can also play with your friends in a 4-player split screen mode. It works perfectly for couch playing, try it out!

A happy crustacean hits harder than a ton of bricks. Just like in real life, a crustacean becomes more powerful as he is filled with serotonin. When his meter is full, he transforms into a dangerous wrecking-ball version of himself. Pretty simple.
