Hidden Parts:
There are 20 hidden parts listed. To get all 20 you must either "find" the part within the mission OR complete certain criteria in a mission to get the part after the mission is completed.

** MLH-MX/VOLAR **
Type: Performance
Location: Garage
Mission: AC Test 1
You must get an S rating, about 45 targets in AC Test 1.
Special Consideration: You only have to hit each target 1 time, use a sniper rifle, or any single shot weapon of your choice. Accurace, time, and number of targets all count. 

** CBT-FLEET **
Type: Find part
Location: 1st Layer: Nature Area
Mission: Destroy Massive MT
In the Northwest corner there is a small nook, the part is in the middle of that, it’s a black spec on the ground.
Special Consideration: It’s best to pick this part up as you start the mission, as the Massive MT is on the other side of the area. If you use a consort you won’t be able to get the Moonlight. You may try to get the Moonight after you beat the game if this is too hard right now.

** MLB-MOONLIGHT **
Type: Performance
Location: 1st Layer: Nature District
Mission: Destroy Massive MT
Successfully complete the mission without using a consort.

** MWI-DD/20 **
Type: Find part
Location: 1st Layer: Nature Area
Mission: Defend Water Processors
You will find the part on the other side of the pipes to the right of you when you start.
Special Consideration: Hover legs very useful for this mission. Also, consider taking the second half of this mission as it also gets you another part.

** KES-ES/MIRROR **
Type: Performance
Location: 1st Layer: Nature Area
Mission: Defend Water Processors
Complete the second half of this mission to get the part.

** MWG-SBZ/24 **
Type: Find part
Location: 1st Layer: Nature Area
Mission: Recover Ship Cargo
You will come to a large room with two doors, one door leads to your target, the other to the part.
Special Considerations: A fast AC with Radar and Mapping abilities are a must.

** KWB-MARS **
Type: Find part
Location: 1st Layer: Nature Area
Mission: Destroy Massive Weapon
The part is located on one of the beams just above the water of the platform you start on. It’s on the side that you are facing when you start the mission.
Special Consideration: The part is right above the water line and you have nothing to stand on, so hover legs could be used without falling in.

** MWG-XCB/75 **
Type: Performance
Location:1st Layer: Special Research
Mission: Defend Ruglen Laboratory
Defeat the AC and successfully complete the level.

** CEEC-01-XSP2 **
Type: Performance
Location: 1st Layer: Special Research
Mission: Eradicate Life Forms
You must destroy the life forms without using the gas canisters. Your best bet for this is a tank legged AC with a powerful sword. I used the Moonlight and it took 3-4 hits to kill one.

** KWX-OC-22 **
Type: Performance
Location: 1st Layer: Special Research
Mission: Destroy Germ Canisters
You must kill all the MT’s and opposing troops as well as successfully complete the mission.

** MRL-SS/SPHERE **

** MWG-KARASAWA **
Type: Performance
Location: 1st Layer: Special Research
Mission: Destroy Gun Emplacements
You must finish the first mission in a short amount of time. Just go for the gun emplacements don’t worry about the camouflaged MT’s. Then you must accept and successfully complete the second part of the mission.
Special Considerations: The second part of the mission is a constant onslaught of MT’s, for a long duration of time. A Heavy Semi mobile humanoid is recommended here. Take a lot of ammo.

** MEST-MX/CROW **
Type: Find part
Location: 2nd Layer: Waste Disposal
Mission: Disable Pulse Generators
There are 4 generators, and two of them are in ducts. Near the generator in the duct in the lower of the two large rooms there is a duct that goes up around the generator. In that duct you will find the part.
Special Consideration: Remember that the goal of the mission is to disable the generators, all other opposing forces are distractions from your main goal.

** RMR-ICICLE **
Type: Performance
Location: 3rd Layer: Industrial Research
Mission: Defend Personnel Convoy
You must successfully complete the mission without losing any of the convoy.
Special Considerations: You do not have to take the second part of the mission to get the part. You need to be able to stop the opposing MT’s fast. Also, note that once you clear the area of the current MT’s more MT’s will appear in two’s from the tunnels farthest away from you, so you might want to consider sitting near two tunnels and running in when the MT’s appear to control where they come from.

** CHD-04-YIV **
Type: Find part
Location: 3rd Layer: Industrial Research
Mission: Defend Naire Bridge
Go to the end of the first part of the bridge, where the bridge gap is. If you fly down and under the bridge back toward the start location you will see the part on the edge of the bridge.

Move toward your right along the top of the dam, the part is right behind the first structure.

** KWM-AD-50 **
Location: 3rd Layer: Industrial Research
Mission: MT Training Exercise
You must complete the mission without getting hit.
Special Consideration: If you are having trouble dodging every single missile there is a simple way to do this mission. Equip the inside part MWI-EM/15, and the back weapon part MM-AD/20 on both back slots. Then as the mission begins move your FCS window up and fire off 1 of the inside parts, don't move, just sit there. After you see it blow up, quickly fire off another. If when you fire one off and it explodes immediately, look a bit higher. Using the Crow Extension is also infinatley helpful. Thanks to Timerlane for the tip!

** CEBT-HEX **
Type: Performance
Location: 3rd Layer: District 1
Mission: Safeguard Alloy Sample
You must complete the mission without losing the transport.
Special Consideration: There is an AC that you must defeat rather swiftly or else the transport will move on and get blown up by some MT’s. You best bet is to clear as far ahead as you can.
