Final Fantasy VII Remake - Battle Intel Guide

Ifrit

You will get Ifrit by default from Jessie, just before your second mission with Avalance group.

Chocobo & Moogle Materia

This one can be found in Sector 4 - Plate Interiror, Plate Middle Level, before you ride the final elevator after turning of 3 generators. West (if you look at the map) of the main elevator on this level is a moving platform which requires you to turn off at least 2 generators in this area. Ride that one, climb the ladders and interract with the computer here. You need to defeat all the enemies in the room and interract with another computer to open the next door. Do not worry, if you fail you can still retry. This will turn off the ventilation and you can now pick up the materia (you see this one when you travel through this area).
