Operation guide: TR-17
| Operation | Guide | Story |
The seventeenth tutorial operation in Arknights, TR-17 explains the mechanics of the newly introduced Guerrilla enemies, particularly the "Inspire" ability.
After Dobermann finished her explanation, Beagle and Perfumer will be deployed at C3 facing right and D4 facing down, respectively just as two Guerrilla Fighters and a Guerrilla Sniper spawns from E9. Beagle should be able to hold them off, but a Guerrilla Herald will spawn from E1. Dobermann then points out that the presence of Heralds "inspires" all enemies by increasing their ATK and DEF, and activating most Guerrilla enemies' special abilities, which can be noticed by the Guerrilla Sniper now hitting Perfumer as well – the Sniper can attack two target at once when Inspired.
Jessica will be automatically deployed on E5 and should be able to kill the first Herald without issue, but then two additional Heralds will spawn: one from E1 and another from E9. At this point, Amiya and Melantha will be available for deployment; use what the player had learned so far to dispatch the Heralds to prevent the Guerrilla Fighters and Sniper from overwhelming Beagle and Perfumer with their buffed ATK.
