Compared to Armored Core 4, the Nexts in are much faster. The quick boost thruster consumption appears to have been reduced, resulting in quite a few of the AI to move very quickly and erratically. Tried and true methods that brought down Nexts in Armored Core 4 do not always work, such as the ever potent HLC02-Sirius. The developers have compensated for this by giving players the back chain guns GAN-01-SS-GC, which is acquired by following the Collarred story line. Combined with the INBLUE FCS, which has the highest lock speed, and rapid boost techniques to stay close, you can easily destroy almost any Next. Unfortunately this is not available until after the Defeat White Glint and Defend Line Ark missions, which are very difficult without these chain guns on your back. Only a fewNexts utilize aerial combat techniques; Fragile, White Glint, Ambient, Stasis, Old King, and Unsung. Additionally, laser blades can use lock on now making it easy for Nexts to target you with their blades. Shinkai is the most dangerous and is found in the Defend Arteria Cranium (final mission for Collared) and can rapidly take you down to size using homing strikes from the 07-Moonlight.
Try the following equipment:
Category 1 Load (allows heavier Nexts)
Category 2 Energy Output (more energy for flying and energy weapons)
Category 4 KP Output (greatly enhances Primal Armor)
Category 2 Core (another great boost to Primal Armor)
Category 1 Main Thruster Horizontal Thrust (increases speed and flight time)
INBLUE (400 lock speed but shorter radar and lock ranges great for fast moving enemies)
063AN05 (200 Lock speed medium lock and radar range, highest ECM resistance)
GAN02-NSS-G (High output, capacity, very high KP output for primal armor, and it is fairly light
Main: Duskaror-Corb (not the fastest but it is quick, light, and has very good horizontal consumption)
Back: 03-Aaliyah/B (not the fastest for regular flying but very good quick boost and decent energy consumption for regular flight)
Side: AB-Lahire (fast, good consumption, good quick boost, and light)
OB: KRB-Lahire (light, decent speed and consumption, one of the better Assault Armors)
ORCA story path
To unlock the ORCA story path, beat the "Defeat Red Rum And Stark" and "Destroy Megalis" missions in chapter 3.
Easy "S" rank on "Attack On Arteria Cranium":
Use the following strategy in Attack On Arteria Cranium (Hard difficulty setting; Blade strategy). You may have a hard time going against three ACs with no support. Try out this build. It is typical, with most parts acquired through the story by getting "White Glint". You need a total (as of now) 389 FRS Memory Points. This build is very fast, hits hard, and all you have to do is use hit and run booster techniques.
Max ARGYROS/G: Energy Output, Energy Capacity, KP Output. Do not worry with load, as you will be fast and extremely agile. You will be nowhere in the caution or overloaded area.
Scroll across to "Primal Armor" and max all four slots. The remaining points can be supplied to the "Acquisition" if desired, for lock-on speed.
R Arm Unit: 07-Moonlight
L Arm Unit: 07-Moonlight
R Back Unit/ L Back Unit: ACB-0710 (replaces both the R/L Back Units)
FCS: BLUEEXS (perfect for blading)
Generator: ARGYROS/G (plenty of energy with above tuning)
Main Booster: MB11-LATONA
Back Booster: ARGYROS/B
Side Booster: AB-LAHIRE
Overed Booster: GAN02-NSS-O.CG
This AC configuration offers infinite flight, regardless of prior tuning. It is a heavy weight AC that has plenty of AP. Note: Weapons are not in the layout to allow personal preferences. Regardless, this AC schematic has multiple advantages outside of its flight capabilities, such as its large hangers that can hold larger weapons.
