FULL METAL COFFIN is 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 specially built using the latest in material science to withstand the unique conditions posed by this new environment. Crew your vessel with up to 4 players. Load the torpedoes, dodge incoming fire, and eliminate the enemy. 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. FULL METAL COFFIN has most of what it needs already. If the dev wants to expand on it, a PvP mode or a roguelike mode could work really well, where players go in and earn upgrades for the sub like movement speed, turn speed, special ammo types, upgraded ammo, interior upgrades that make things faster or more efficient, better radar, and plenty of other possibilities.
Anyway, if this sounds interesting—especially with a group of friends—it can be a lot of fun, so it’s easy to recommend in its current state. The only notable issue is frame rate drops. Even after lowering render scaling and other settings, the frame rate would still drop whenever outside of the menu screens in FULL METAL COFFIN. Ideas: Different escape points at the end of each map, making players dodge or fight multiple other subs to reach extraction.
A multiplayer PvP mode would be incredible. Since players can’t directly see each other, combat would revolve around detection, making for tense encounters. Having subs take around five torpedoes to sink could help balance fights. AI subs could also roam the map collecting scrap, encouraging players to craft different types of torpedoes. FULL METAL COFFIN is a really fun game with a ton of potential. A great launch, and with continued development, this could become something special.
