# ORCA story path
In Chapter 3, successfully complete both the "Defeat Red Rum And Stark" and "Destroy Megalis" mission to unlock the ORCA story path. The first ORCA mission is "Destroy Arteria Ulna".
# AI
Compared to Armored Core 4, the Nexts are much quicker. The quick boost thruster consumption appears to have been reduced and this causes quite a few of the AI to move very quickly and very 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 placers the back chain guns GAN-01-SS-GC obtained by following the Collarred story line. Combined with the INBLUE FCS, which has the highest lock speed, and rapid quick 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. Very few Nexts utilize aerial combat techniques; mainly Fragile, White Glint, Ambient, Stasis, Old King, and Unsung. Also, 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 very quickly take you down to size using homing strikes from the 07-Moonlight.
# Recommended equipment
FRS distribution
Capacity
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)
Primal Armor
Category 2 Core (another great boost to Primal Armor)
Boost
Category 1 Main Thruster Horizontal Thrust (increases speed and flight time)
FCS
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)
Generator
GAN02-NSS-G (High output, capacity, very high KP output for primal armor, and it is fairly light)
Thrusters
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)
# Custom AC
The following AC configuration will give you unlimited 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. This AC schematic has its various advantages outside of its flight capabilities, such as its large hangers which can hold larger weapons.
