Armored Core 2 Cheats
If you want to give your contribution, you can submit your cheats using this form
If you press L2 + R2 + R3 during the game, you'll have unlimited energy for a brief period of time. Finish off your enemy before the end of this period, because your Core will need about a minute to recharge and return normal. And in this minute it will be completely defenseless.
Add defeated AC emblems
Press Select + Start when the victory message appears in the arena to add the defeated AC's emblem to your list.
If you see an emblem in the arena that you want to use, select the appropriate AC and press Triangle to display the spec screen. Then, press Start + Select. A sound will confirm correct code entry. Select "Edit Emblem" to view it.
Intentionally lose the first mission after the Raven test, then die with -50,000 credits or less to activate additional cheats. The more times this is done, the more cheats you will unlock. Better radar, fire projectiles from laser swords, cooling twice as fast, being able to fire rear weapons while in motion, and double available energy are just examples of the hidden cheats you'll activate in this way. Notice that you'll restart from the beginning the game.
