In order to acquire the Pescaphobe Trophy, you must kill all 15 catfish. Now, this is not an easy task. You’ll need precision and complete determination to do so. You might die at first, maybe a couple of times but if you have patience, you can achieve this.

1. Kill the first catfish

Then swim your way up.
Note: You must move fast for you’ll need to refill your oxygen.

2. You will see an open hole where bubbles (oxygen) are leaking through a pipe.

The Blue Color in the bar indicates that you have enough oxygen to move on. Whenever this turns red, locate another leaking oxygen pipe to get some more air.

Hint: The next catfish is located at the right side of the hole.

3. Now, roam around the place and search for more catfish but be sure that you have enough oxygen to continue.

Hint: Most of the catfish are located near the leaking pipes.

4. In some parts, you will see a valve.
Hint: If you can’t turn on the valve, swim back for a few meters away then plant a bomb.

5. Continue searching for the remaining catfish. Make sure that you won’t die for the whole mission will restart meaning the fish count will be back to zero.

After killing all 15 catfish, you will now earn the Pescaphobe Trophy!
