Esteemed Avalanche Colleagues, Gain Intel, and Scout Out Sector 7 are the second, third, and fourth quests in Chapter 1, "Wutai's Finest", of "Episode INTERmission" in Final Fantasy VII Remake. "Gain Intel" has the subquests Billy Bob, Polk, and Nayo, while "Scout Out Sector 7" has the subquests Combat Simulator and The Happy Envoy. Yuffie Kisaragi arrives in the residential area of the Sector 7 slums, where she sees Scarlet being interviewed following the destruction of Mako Reactor 5, and deduces that Avalanche were responsible. After this, she is met by Zhijie, who shows her around.
Walkthrough[]
Esteemed Avalanche Colleagues and Gain Intel[]
Boomerang is in a treasure pot.
Follow Zhijie to the Sector 7 Clinic, Avalanche's base, where a bench will restore HP and MP. Descend the stairs and approach the other members of Avalanche: Billy Bob, Polk, and Nayo, for a cutscene to commence. After this, the 
Boomerang can be acquired from a treasure pot in a corner (in a repeat playthrough, this is a Potion instead). This weapon teaches the Brumal Form ability, has an additional materia slot when acquired, and in attributes, sacrifices 
Attack Power for 
Magic Attack. The three Avalanche characters can all be talked to for different dialogue to proceed.
Fort Condor[]
Polk challenges Yuffie to Fort Condor, and gives a Fort Condor starter pack. In the game, each player has a loadout of units they select at the start, and three bases to defend. With the starter pack given by Polk, the loadout of units is set automatically. Units are deployed based on the player's ATB, which fills up over time; when enough bars are available for a unit, it can be deployed from the loadout by moving the cursor to the desired spot, pressing 
to open the menu of units, and selecting it. Vanguard units are effective against ranged units, ranged units are effective against defense units, and defense units are effective against vanguard units. Magic Attacks can also be used (depending on the board); different attacks do not deal elemental damage, but do have different patterns.
The battle against Polk is fairly straightforward. Simply deploy units to counter his; when deploying an available unit, it will indicate over enemy unit's HP bars if the unit is advantaged against them or if the enemy is advantaged against the unit. Follow this, and place the strongest unit available (indicated by the higher number) to defeat the enemies.
After beating Polk, further challenges are available in the sidequest "Mastering Fort Condor", though Polk can be challenged again to repeat the tutorial match.
Scout Out Sector 7[]
Warding materia.
After beating Polk, the remaining quests involve talking to other non-player characters. Talking to Chadley will unlock the "Chadley's Research" sidequest. Talking to the Old Snapper, located in the southern end of Sector 7 slums, will open the Condor Coin Shop, in which Condor Coins can be traded for items and for Fort Condor units and boards. He also opens the sidequest "The Happy Turtle Ad Campaign", where Yuffie can find six flyers around town to score a 
Magnify Materia as a reward. During the quest, Yuffie can pick up a Warding Materia by heading through the tunnel to the house at the center of town, near to where a woman is telling children a story. At the Abandoned Talagger Factory, also visited during the quest, a 
Chakra Materia 
and a 
First Strike Materia can also be picked up.
The Junk Shop in the tunnel behind Seventh Heaven changes its wares every time you advance in a quest or initiate a Fort Condor game, so it is worth checking back there frequently to find everything he has to offer. There is a chest containing a Riot Trooper Barracks (Defense) for the Fort Condor minigame near to Wedge's residence.
Upon talking to both Chadley and Old Snapper, return to the base for a cutscene, commencing the next quest, "The Handoff".
