Submarine Survivor

Submarine Survivor is an action game in which you pilot a submarine through a dark ocean, fighting waves of sea creatures and completing mission challenges. Each run takes you across a map of mission nodes before a final boss encounter.

Missions and progression

Missions last about 10 minutes, and your progress carries over between them. You accumulate upgrades and resources as you prepare for the final boss. Completing missions raises your threat level; when it fills, the final boss takes notice, and you decide when to face it.

Submarines and upgrades

You can unlock different submarine models, each with its own characteristics, and customize and upgrade them to suit your playstyle. Upgrading the submarines can also benefit your entire fleet. You can research passive upgrades and craft equipment to gain strategic advantages.

Crafting and difficulty

Collect resources during explorations to craft items, then upgrade them and customize their attributes to improve their combat effectiveness. Choose a difficulty to suit your skill level. Higher difficulties strengthen enemies and add modifiers that change how each run plays.
