For those who couldn't make it to the stream, you can still add Nyx to your Arsenal by completing four in-game Alerts between December 12 at 5 p.m. PT and December 19 at 8:59 p.m. PT. These will each offer one of Nyx's crafting components for free:
- First Alert: Nyx Blueprint
- Second Alert: Nyx Systems
- Third Alert: Nyx Chassis
- Fourth Alert: Nyx Neuroptics
