A playlist of the soundtrack used for Armored Core, and Armored Core: Project Phantasma for the PS1. There's only a few from Master of Arena because I don't want to hit the limit for future uploads.

Armored Core PSX OST

mmmmmmm

No one else uploaded the one from AC1, so have this.

All rights go to FromSoftware, I only uploaded this so that others could listen to this and the rest of the game's soundtrack in Soundcloud.

High Fever Album Version - Armored Core Soundtrack

Response～Infraction - Armored Core Soundtrack

The one playing ingame. 

So far, only the album version was uploaded until now.

Shape Memory Alloys Game Version - Armored Core Soundtrack

Dotted Line - Armored Core Soundtrack

Junk Mail - Armored Core Soundtrack

Much like High Fever from AC1, this was missing in Soundcloud.

All rights go to FromSoftware as usual, only uploaded here so people can listen to it here.
