Well, now that I've got that song stuck in your head, let's take a look at DeepWars. AntiMatter Games is running a Kickstarter to expand their DeepWars line, including a new submarine as well as various other sea creatures and characters.
From the campaign:
This Kickstarter will help us produce new resin submarines for DeepWars, our game of underwater combat and exploration. The focus of the project is on the first of the planned submersibles, the Argonaut, as well as new miniatures for the game supplement, Blood Reef. The model for the Argonaut has been sculpted in 3D and is almost ready for production. The model is 200 mm in length and scaled for 30mm gaming.
The submarine will come with a detailed coral reef base and will have a full cockpit interior with windows cast in clear resin to allow for viewing of the pilot.
We are also producing new miniatures for DeepWars...
