Try To Reach The Abyss Torpedoes Guide: What Torpedoes Do and How to Upgrade Them

Torpedoes are your submarine's weapon in Try To Reach The Abyss. Firing torpedoes is tied to collecting Research Data, which unlocks abilities, and the depths are full of dangerous sea monsters — so stronger torpedoes directly support both fighting and progression.

How to upgrade torpedoes with upgrade points

Upgrade points come to you for free: reaching the next outpost rewards you with one. You then decide which of the three upgrade categories it goes into — Speed gains, hull, or torpedoes.

1. Travel to an outpost and step out near the upgrade stall.
2. A proximity prompt appears — press E to open the Upgrade Store.
3. The store shows your available Upgrade Points at the top.
4. Find the TORPEDO DAMAGE entry, which reads "Each torpedo hits harder."
5. Press the UPGRADE — 1 POINT button to spend one point on it.

For comparison, the same store lists UPGRADE RATE for Speed gains ("Earn Speed more often") and HULL for your submarine's health ("More health for your submarine"), each with its own one-point button. The choice is yours each visit — torpedo damage is simply one of the three places every point can go.

What torpedoes do for your run

The game pairs torpedo use with Research Data collection: firing torpedoes and collecting Research Data unlock abilities. Because the seas also hold dangerous sea monsters among the discoverable locations, having harder-hitting torpedoes makes the combat side of exploration more comfortable as you push deeper.

If you're deciding how to spend your first points, note that upgrades feed different parts of the loop: hull keeps your submarine alive, Speed rate accelerates leveling and travel, and torpedo damage strengthens your offense. Points are earned one at a time at each outpost, so you'll naturally revisit the store throughout a run.
