From the campaign:
AntiMAtter games has ust started the ShadowSea -Battle for the Underlands kickstarter run! This takes the combat above and below the sea, with rules that are compatible with DeepWars. Players can have land and sea adventures, exploring submerged citadels with air-filled and flooded sections using mixed warbands or marine and terrestrial warriors. We will be adding a new video soon with more art and information. Minis are being sculpted already so we will show some WIP sculpts later on.
