Steam download path

  1. Open the AION 2 Steam page.
  2. Use the Playtest access entry for the Launch Scale Test. The official test announcement links to Steam app 4972320.
  3. Install the Playtest build once pre-download opens.
  4. After Day 2, uninstall the Playtest App. NC says the regular AION 2 app must be downloaded separately for September 30 Advance Access.
Important:

The test build is not the same install you keep for launch on Steam.

PURPLE download path

PURPLE is an official test platform alongside Steam. Install/update PURPLE before the window, sign in with the NC account you plan to use, and use the AION 2 test entry when pre-download opens. NC specifically says PURPLE players have no extra uninstall step after the test.

How much disk space to clear

Steam lists 100 GB of available storage for the main Global client and recommends an SSD. The current Steam Playtest depot snapshot is about 80.42 GiB to download, but it is not a final retail-client promise. Track AION 2 download size →

Do you need a Founder’s Pack?

No. The Launch Scale Test is open to everyone and Founder’s Pack items are disabled during the test. Packs matter for five-day Advance Access beginning September 30, not for access to the LST.
