Hint: Cavern Invasion level:
There is a hole in the ceiling at the top of the first room. Fly up to it and
take a left. There will be a very large room with guns mounted in the ceilings.
Do not shoot at the guns. Instead, go directly for the left corner in the back,
where an item will appear on the ground. This is the shoulder mounted disc
shooter.
Hint: Destroy Berserk MTs level:
Get past the first locked gate and find the door on the left side that follows
it. Follow the corridor until you find a room full of gray crates. Do not shoot
the crates or you will blow up the item. Maneuver around the crates until you
find a corner with a head part on the ground.
Hint: Find a FCS part:
In the level that you help your MTs there are three yellow ones and six gray
enemy ones. There is a building in one of the corners with columns in the front
of it. Blow it up. Enter the hole under where it was located. There will be
three dead ends in there, one of which can be destroyed. Search inside to find a
part of an FCS.
Hint: Find Prize Parts in the Arena/Sub-Arena:
If you have played Armored Core: Project Phantasma, you will know that you will
get a free part when you defeat a certain ranking Raven. However, unlike Project
Phantasma, Master Of Arena will throw more ranking Ravens at you even after you
defeat all of the Ravens listed. Keep checking back in the Arena/Sub-Arena to
make sure that you have fought everyone to be sure that you do not miss any
prize parts.
Hint: Prizes in the Leg Specific Ex Arena:
If you go into the Ex Arena, you will see that there are four arenas that are
leg specific. This means that you can not take a caterpillar (tank) style AC
into the humanoid arena. The good news about these leg specific arenas is that
as you conquer each one, you will get a leg part that is from the arena type you
just completed (humanoid-humanoid, four leg-four leg, reverse joint-reverse
joint, caterpillar-caterpillar).
Hint: Stealth unit:
Complete the Master Ex Arena to get the stealth unit (back weapon). This item
will take you off the radar and is probably only meant for two players.

Creed.
Hint: Enhanced Balancer Optional part:
complete the Champion Ex Arena to get the Enhanced Balancer Optional part.
Hint: Extra Ex Arenas:
In the Ex Arena selection screen, you will see four sets of question marks if
you go down. These will be unlocked after you complete a certain requirement.
FROMSOFTWARE is unlocked after you complete all leg-specific arenas. It features
a series of ACs made by From Software employees.
Guest and Champion are unlocked after you complete all of the missions (do not
forget to save when prompted). Guest is an arena that contains Japanese magazine
publisher's AC creations. Champion is a series of ACs made by finalists from a
Armored Core: Project Phantasma Tourney held in Japan last year.
Master is an arena that has extremely dangerous ACs. It is unlocked when you get
100% in the overall under System.
Please note that these ACs are not easy to defeat. They will always have an
advantage over your AC regardless of how well armed, armored, or fast you are.
Hint: Overweight override:
The overweight override is present in the game, but there is no penalty for
being overweight.
Hint: Easy way to kill ACs in arena battle:
Equip your mech with the fastest humanoid legs, the new laser rifle arm weapon
that shoots three beams at once, and the new back weapon shaped like a "V".
Select the parking garage as your arena location. This will inhibit the flying
ability of your foe and will allow you to empty all your ammo into them quickly.
In the rare case that they defeat you from excessive swording or close combat,
select the arena with the land mines (with trees outside). Often, they will
start by damaging themselves on these mines to the extent to where you can kill
them with only a few shots, or they will fly out of the area, resulting in an
instant win.
