Load the saved data from Armored Core 2 in the one player scenario to start out with all previously obtained weapons and money.
To activate the Limiter Release, press L1 + L2 + R1 + R2, then press R3 (Overboost). This will put you into Limiter Release mode for around 40 seconds. The only down side is that you get an OB Depletion indicator after the 40 seconds are up, leaving you totally powerless for 50 seconds.
Successfully complete the game, save your data, then load the saved data. You can now access three new high-paying missions where you face Stinger in his AC (from Armored Core: Project Phantasma), Phantasma (who Stinger had merged with), and Final Nine-Ball (from Armored Core: Master Of Arena). All three new missions are very tough. However, you can go overweight for all these missions. After defeating all three, you will get some very fast hover legs, and an "Inside" orbit cannon.
Destroy an enemy AC during a mission to unlock its emblem in emblem edit mode.
