Installing PSO2 NA PC

Phantasy Star Online 2 NA can be installed from scratch in two different ways - Through a store (Windows Store, Steam, or Epic Games Launcher) or the PSO2 Tweaker. The PSO2 Tweaker can switch between versions of PSO2 using one install as opposed to multiple 70GB+ installs, automatically fix issues/problems, remove the ingame censor, filter RMT bots, and much more. This guide will cover installing via the PSO2 Tweaker.

Methods of updating/installing PSO2

# Method Description
1 PSO2 Tweaker By installing or downloading the PSO2 Tweaker, a 3rd party launcher that we've created, you can allow the Tweaker to update the game for you. This is the recommended and most efficient method.
2 Steam You can install PSO2 through Steam by clicking here. If you choose not to use the PSO2 Tweaker, the steam version is recommended. You cannot use this version if you live in the Netherlands Antilles, Belgium, Netherlands, China, Japan, or Republic of Korea.
3 Microsoft Store You can install PSO2 through the Microsoft Store by clicking here. This guide will not cover installing the game via this method. The Microsoft Store version has had issues with the game uninstalling itself or copying itself to locked folders, taking up exponentially large amounts of Hard Drive space. This version is not recommended, for that reason. This version has no region restrictions.
4 Epic Games Store You can install PSO2 through the Epic Games Store by clicking here. This guide will not cover installing the game via this method.

As stated before, this guide will only cover the Tweaker method of downloading & installing the game.
