Bitter Obligation Mission Icon

Bitter Obligation is a mission in Armored Core 4.


  • Area: Exavil
  • Objective: Destroy Target


  • Damage: 24000 AP
  • Ammo Use: N/A
  • Mission Time: 300 seconds


Let's confirm the mission.

Destroy Rayleonard's central headquarters, Exavil.

Exavil is an extremely unique structure. If you destroy the pillars which are set in a fan shape around the facility, the whole thing should lose balance and come tumbling down.

Rayleonard's Nexts have already been exterminated but Exavil is likely still fortified with a tremendous amount of firepower. Don't get cocky.

Those are your orders. This should finish everything.

Special DebriefingEdit

We've received word from Emil. He says that Joshua was successful in destroying Akvavit, too.

So this is the end of the Lynx war... So many people dead, and the environment in shambles all for such selfish reasons.

It might still be going on right now, if not for you. You've done well... Thank you.

Let's go home, back to Anatolia.


The mission objective is to take down Rayleonard's HQ, Exavil, by cutting the pillars supporting the upper structure. Destroying Rayleonard has the potential to end the LYNX War.

The last of Rayleonard's standing armory is present here.


Rayleonard has salvaged an 002-B for this mission, along with a handful of naval destroyers and several 044FV450 Normal emplacements. The only real threat is the 002-B's large Kojima blade, so keeping on the move is essential to avoid it.


Fiona Jarnefeldt:Your objective is Rayleonard's headquarters, Exavil. This is the last of them. Let's get to it.

Fiona Jarnefeldt:Exavil pillar successfully destroyed. The facility's balance has begun to falter. We're looking good. Continue removing the pillars.

Fiona Jarnefeldt:Exavil pillar destroyed. You're doing great. Keep an eye on enemy troops and continue like this.

Fiona Jarnefeldt:Another of Exavil's pillars destroyed. The facility is nearing its limits. Keep at it.

Fiona Jarnefeldt:All pillars have collapsed. Shock detected within Exavil's core facility! It's starting to fall. Get out of there!

Fiona Jarnefeldt:Exavil is falling. Mission accomplished. Rayleonard is gone. When did things escalate to this? At least this is the end. Good work. Please head back.


Ignore all other enemy targets, and go straight for the pillar supports. Any weapon will tear them apart, but keep moving to avoid fire. After several struts have been hit, the structure will collapse and end the mission.
