To see how the 25 feeder answers can be grouped into 5 groups of 5 answers, one for each meta puzzle, refer to the solution page for “Base of Operations”.
This puzzle uses the category “KTANEy words that contain other KTANEy words”. The boxes near the top of the page hint at words containing other words. The “inner” words then connect to the clues, leading to further answers, from which letters are extracted as the lines suggest.
|SWITCH||same letter, but same row as 2 (Sea Shells)||TOUCAN||TOU|
|Note that the red boxes hint that it also contains WITCH and ITCH, but not to use those.|
|PASS||what’s above that (left of the display) (Tic Tac Toe)||UP NEXT||UPET|
|TROLL||what it has 8 of (Adventure Game)||STRENGTH||TNGH|
|EVOLVE||four down, one right (Extended Password)||NEBULA||NBL|
|PORT||the only one with 8 letters||PARALLEL||ER|
Putting the letters in the correct order as indicated by the lines yields the solution.
