Burst Missile
When you convert your saved game data from Armored Core: Nexus into Armored Core: Nine Breaker, the Burst Missiles disappear. However, if you start a new game in Nine Breaker, the Burst Missiles remain in the garage.
Instant training mission completion
In Training mode there is a exercise called "Attack Hit: Single"; the glitch is in level 3. In the beginning of the round, fly up with the enemy AC and keep him in your sights. After about eight seconds, both yours and the enemy's AC will stop moving and fall to the ground. The operator will speak in Japanese, then a message will say that you have completed the mission. Your results will be a "Gold" rank in first place.
Part tuning
To tune parts (only applicable with head, core, arm, leg, booster, generator and radiator parts), press Square while in the "Assembly" screen.
