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 151 to 223. This was probably due to the intruduction of the Discharge Heat stat only appearing in Another Age.
  • This is the most inexpensive core part in both games it appears in. It also has the lowest OB Energy Drain in both games although it is tied with the ECH-D4.
  • In Armored Core 2: Another Age, the OB Energy Drain value remains 18000, but this is false (it was only true in Armored Core 2). It now drains more energy; the value should be somewhere around 22000.
