The Razorback Armada is an event produced by the Corpus to assault a relay. Here is how to participate:
1.) Obtain Cryptographic ALU’s - These drop from Archwing enemies on the missions Galilea Jupiter / Salacia Neptune.
2.) Craft the Razorback Cipher and equip it via Gearwheel in your arsenal.
3.) Start the mission.
4.) Get to the arena door and hack the terminal with the Cipher.
5.) Hack into either of the two terminals in the upper balconies of the arena, then attack the bursa that spawns below; you’ll need to incapacitate the bursa then hack the panel on its backside.
6.) The hacked Bursas will then attack the Razorback and allow you to damage/kill it while it is down.
7.) Repeat steps 5-6 until the boss is dead, and then extract from the mission.
The event rewards 200,000 credits and an Orokin Catalyst upon successfully killing 3 Razorbacks. Here are the Drop Tables for extra rewards, such as the Gorgon Wraith.
