# Meta Quest 2 (Unity 6.3 LTS)
> [!important] Version requirement
> **Unity 6.3 LTS (6000.3.27f2) and newer.** Package versions in these notes are what the Unity 6000.3 documentation listed in Nov 2026. Open Package Manager and trust it over this note.
> [!warning] Quest 2 is in its end-of-feature-development phase
> Meta has said Horizon OS v2.13 is the last feature OS for Quest 2 and Meta VR OS SDK v213 is the last SDK that supports it. Security fixes continue through Dec 2027, and new Quest 2 app submissions are accepted through Dec 2027. Details and sources in [[1.Quest 2 Support Status]].
> [!note] How this was verified
> Facts come from the linked Unity and Meta pages, read in Nov 2026. Scripts in these notes were **written but not compiled in an editor**; treat the first build as a test. Items I could not confirm are marked **(unverified)**. Part of [[VR]].
## What you will build
A small VR room for Quest 2: teleport locomotion, grabbable objects, and a **world-space control panel built with UI Toolkit** (not uGUI), using XR Interaction Toolkit (XRI) 3.x on OpenXR. The same project builds as an Android APK for the headset and tests in the editor over Meta Horizon Link or the Meta XR Simulator.

## Before you start: which Unity version?
> [!tip] [[0.Choosing a Unity Version]]
> This series targets **Unity 6000.3.27f2+ (6.3 LTS)**. Unity 6000.4.x and 6000.5.x are not recommended: they are end of life, have no patch for the October 2026 security advisories, and have reported Meta SDK build breakage. See [[0.Choosing a Unity Version]] for affected versions, sideloading risk and SDK compatibility.
