Armored Core 2: Another Age


  • This part got a stat increase in Armored Core 2: Another Age. Its OB Limit was decreased from 2400 to 1200 and its overall Over Boost performance was raised from 190 to 260. This was probably due to the introduction of the Discharge Heat stat only appearing in Another Age.
  • This is the lightest core part and the one with the lowest Def Shell, lowest Def Energy, lowest Defensive Points, highest Over Boost and lowest Cooling in both games it appears in. In Another Age it also has the lowest Discharge Heat value.
  • The core part CR-YC010/UL2 from Last Raven is a Replica of the ECL-ONE.
