About What'Sub

✦ AI summary

What'Sub is a 1-4 player co-op extraction diver where you pilot a decrepit submarine into the Bermuda Triangle's depths, balancing greed against survival as you loot ancient treasures and race back to the surface before everything falls apart. Every dive features procedurally generated caverns and wrecks to explore, permadeath consequences that make every decision sting, and a submarine held together by prayer and duct tape that demands constant maintenance from your crew.

What'Sub is a 4-player co-op submarine extraction game where you pilot a rust-bucket submarine into the depths of the Bermuda Triangle to recover treasure from the ocean’s seafloor. Gear up, descent, risk everything to bring your haul back to the surface, then dive again to ever deeper levels.

✦ AI summary

What'Sub is a submarine exploration game with multiplayer focus that players praise for its charming hub world, cozy atmosphere, and the development team's rapid improvements and optimizations. The main draw appears to be exploring the ocean with friends in a gameplay loop reminiscent of early Sea of Thieves, though players note there are still bugs like out-of-bounds exploits and incomplete features like fishing. Most reviewers express optimism about the game's potential and recommend it for casual play with one or two friends, viewing it as worth trying while it continues development.

REDUCED BUILD SIZE BY 70%. Call this dev team the optimisers. My early impressions are that this team is quickly working towards improvements and adding fun silly things into the game. I've only seen the difference since last patch but small things like improvement to the ui are noticed and greatly appreciated. Even small game balancing to come closer to a specific vision that the devs wish to achieve gives me great faith in the team. The fans in the base to move around? Brilliant. When fishing (and combat with those pesky crabs) gets implemented, we will truly be gaming. Future looks bright.

Can easily get out of bounds in the hub. 10/10 even after they patched my old path, theres always new ones. Otherwise, this is a game with promise. The gameplay loop is similar to very early Sea of Thieves, just under the water, so its a formula thats already proven to be good. And heres a decent Indie game attempt at solving it. Would recommend for people with 1-2 friends that can play.

Very fun friend-slop game! Met the devs at Gamebox and won a copy of the game. Really looking forward to seeing it "fully" finished, it's already very pretty

Had a great time exploring the oceans with my friend. Couldn't hook those pearls for my life! Also, the Hub-world was so cozy! Loving these NPC designs.
