Ah so you’ve reached the second reactor in Final Fantasy 7 Remake (well sort of) and it’s time to deal with Heidegger and President Shinra’s Airbuster (well almost). First, you absolutely should take advantage of the ability to rip off some of the parts of the Airbuster before you fight it to make your life easier, and cash in a bit. Only one keycard per set of terminals is required to progress, but you can find more keycards to weaken the Airbuster even more. Here are all the Keycard Locations at the second mako reactor in Final Fantasy VII Remake.
If you scroll below you can find all of the keycards that you can possibly pick up during this section at the second Mako Reactor. First though, before you go ahead and follow along let’s talk about what the terminals actually do and which you should pick.
The AI programming core reduces the speed in which the Airbuster will use its stunning electric finger attack (which covers a whole line and is quite annoying). The Big Bomber Shells will reduce the number of times it uses its massive area attack and the M-Units will give you supplies if you recover them by doing the optional lever section after the keycard recovery with Tifa and Barret before the fight.
It’s not going to be life or death either way, but your best bet is probably knocking out the AI Programming Cores and then deciding between the M-Units and the Big Bomber Shells. Personally, I left the M-Units alone aside from the one you have to pick and split between AI Programming Cores and Big Bomber Shells.
Not only are the electric finger attacks quite annoying during battle, but each AI Programming Core you collect can be sold for 500 Gil after the fight which isn’t too shabby at this early part of Final Fantasy 7 Remake. That is, of course, assuming you go to collect everything you’re dumping when you reach the lever pulling segment. Which by the way, you totally should.
The Big Bomber Shells will turn into items you can throw at enemies for damage, which is OK but I personally preferred just getting the Gil as the bombs are worth nothing at a shop. The M-Units don’t help you at all in battle, and only provide you Ether. If you have a need for them then go for it, but you should have plenty if you always buy the reduced cost ones from the Vending Machines.
