ARMORED CORE VI FIRES OF RUBICON How to Beat IB-01: CEL 240 Boss Battle

CEL-240 is the most difficult boss battle in the whole game, because after many easy missions everyone comes unprepared to encounter it. She is truly artificial daughter of Malenia and Malekith, who sealed her brain in a magical stone, in order to create a weapon of destruction millions of years later. You, tranished one, should be grateful for the generosity of “Let me solo her”, who spared their daughter so that you could get a solid beating again in the next installment of the game.

Cool copium story, but how to actually beat her?

1. You want to end the war fast, so you need to borrow all javelins or heavy cannons. Everything that does HIGH dps instantly will work. Also you need to be fast and act fast, so make the fastest AC on the Rubicon, became the real F1 car. Personally I find EL-TL-11 FORTALEZA the best for that fight, because by driving around CEL-240 you don’t need to boost in order to dodge her small missiles.
2. SHOOT, literally SPAM EVERYTHING at the moment you enter the boss arena. About 3 Javelin/Stun Needle Launcher/Bazooka/Songbirds strikes are enough to stagger her.
3. Run around till every weapon is reloaded. You can get 1 Shotgun like SG-027 ZIMMERMAN to deal some damage in the meantime.
4. Wait for her to stand in place and repeat point 2.
With a bit of luck you should be able to finish the boss even when you tank every hit.

However, if that’s not enough to for you to git gud and defeat the CEL-240 try learning few dodges
Her triple blade strike is very easy to dodge. The animation is huge and the blade follows your direction, like it predicts your movement. There are no i-frames in Armored Core, so you need to be vigilant and always counter dodge it. When you run to the run, boost to the left before the blade reaches your destination.
The X blade strike is tricky, it’s way faster than her uncharged blade attack. The easiest way to avoid it is to jump or boost foward when she finishes the animation.
The 2nd phase below 50% hp is nightmare for everyone. She is transforming into a bird to make full 3 spins. You can dodge it by hovering at the of spins or by running away before she cast it.
You got only 3 mechstuses, so try to dodge as many attacks as possible.

That’s it for now folks. It took me 3 hours to beat that beautiful lady.
