Load Your Saved AC Form Amored Core 2:

Load you saved data from Armored Core 2 in the one player scenario. You will start out with all previously obtained weapons, money and configuration.

It Ain't Over:

Beat the game and save your data. Now load your save data and you will be able to play 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). Fortunately, you can go overweight for all these missions. All are very tough. After defeating all three, you will get some very fast hover legs, and an "Inside" orbit cannon.

Overweight AC:

Beat the game and save your data. Load the saved data, and you may play missions with your AC overweight.

Enemy Emblems:

Defeat an enemy AC during a mission to unlock its emblem in emblem edit mode.

Save Some Dough:

Go to the back unit section in the shop. Buy the rocket launcher/s with the description, "Large, powerful rockets." They are under 30000 Cr. and are just as good as the expensive ones.
