Short answer: if you already own Another Eden Begins on Nintendo Switch, you do not need to repurchase the full game to access the optimized Nintendo Switch 2 version. Nintendo's official route is the Another Eden Begins - Nintendo Switch 2 Edition Upgrade Pack, which requires the base game and upgrades that version to the Nintendo Switch 2 Edition. Nintendo lists September 16, 2026 as the release date for the pack and both editions.
There are two important cautions for anyone making a purchase decision before release. First, the Brazilian Upgrade Pack page checked on September 11 did not display a price, so it is not safe to state how much the upgrade will cost or to describe it as free. Second, Nintendo describes the enhancements as 4K support and an improved frame rate of up to 60 fps, but it does not say that both targets will be reached simultaneously in every mode or situation.
Quick matrix: what to do in each situation
| Situation | What to do | What you get |
|---|---|---|
| You already own the Nintendo Switch version and want the Switch 2 features | Get the specific Another Eden Begins Upgrade Pack | The Nintendo Switch 2 Edition, without needing to buy the full game again |
| You own the Switch version and only want to play it on Switch 2 without the new edition's enhancements | Use the Switch version on Switch 2 | The game page lists it as supported, with behavior consistent with Nintendo Switch |
| You do not own the game yet and plan to play on Switch 2 | Buy the Nintendo Switch 2 Edition | Under Nintendo's model, the edition bundles the original game and its upgrade pack |
| You will keep playing only on Nintendo Switch | Use or buy the Switch version | The base game; Switch 2 features remain exclusive to the newer system |
What changes on Nintendo Switch 2
The official Upgrade Pack page lists two concrete improvements:
- Enhanced graphics with 4K support.
- Improved frame rate of up to 60 fps for smoother gameplay.
The wording matters: Nintendo says “4K support” and “up to 60 FPS.” The page does not publish the internal rendering resolution, whether dynamic resolution is used, a specific handheld-mode target, or a promise that 4K and 60 fps run together throughout the game. The shown specifications also do not provide an official loading-time comparison. Claiming any of those details would go beyond the information Nintendo has published.
Switch 2 compatibility is not the same as the Switch 2 Edition
The Nintendo Switch version's page says the game is supported on Nintendo Switch 2 and that its behavior is consistent with Nintendo Switch. In other words, owning the Switch game already lets you run that version on the newer system. But that compatibility should not be confused with the enhancements included in the Nintendo Switch 2 Edition.
To access the advertised 4K and up-to-60-fps features, Nintendo points to the Switch 2 edition — either by buying that edition if you do not own the game, or by using the Upgrade Pack if you already own the Switch version.
How much storage does Another Eden Begins use?
Nintendo's Brazilian pages label the file sizes as estimated, and the official listings contain a small discrepancy. The Nintendo Switch version's page currently shows 4 GB for Nintendo Switch and 11.6 GB for Nintendo Switch 2. The dedicated Nintendo Switch 2 Edition page shows 3.8 GB for Nintendo Switch and the same 11.6 GB for Nintendo Switch 2.
| Item | Displayed size | How to read it |
|---|---|---|
| Nintendo Switch version | 3.8 GB to 4 GB, depending on the official page checked | Pre-release estimate; Nintendo's listings differ by 0.2 GB |
| Nintendo Switch 2 Edition | 11.6 GB | The best official figure currently available for planning storage for the optimized edition |
| Upgrade Pack product page | 1 MB | The size shown for the add-on listing, not the total size Nintendo lists for the Switch 2 edition |
In practical terms, anyone planning to use the enhanced version should budget around 11.6 GB based on Nintendo's Switch 2 Edition listing, plus extra room for installation, updates and any changes before release. The 1 MB figure on the Upgrade Pack page should not be used as the total space requirement for the upgraded game.
So do I have to pay for the game again?
Not for the full game if you already own the Nintendo Switch version. The pack page says it is used to upgrade the Nintendo Switch game to the Nintendo Switch 2 Edition, and Nintendo's general Switch 2 Edition model is built around an Upgrade Pack for owners of the original title.
That is not the same as saying the upgrade will be free. When checked on September 11, 2026, the Brazilian page showed the product and release date, but the purchase field was still loading without a visible price. The safe approach is to check the Upgrade Pack price in Nintendo eShop or Nintendo Store when the offer is available for your account and region instead of assuming a specific price or free access.
What to check before buying
- If you already own the Switch version: look for the Upgrade Pack first rather than going straight to the full Switch 2 Edition purchase.
- If you only need compatibility: the Switch version is already listed as supported on Switch 2, but without the new edition's promised enhancements.
- If performance is the priority: the only published promises for this title are 4K support and up to 60 fps; do not assume unannounced modes or targets.
- If storage is tight: plan for roughly 11.6 GB plus some headroom because the figures are still estimates.
- If price determines your decision: verify the Upgrade Pack price in the official store when it appears for your region.
What is still unconfirmed
As of September 11, 2026, the official pages checked did not show a readable Upgrade Pack price and did not specify whether 4K is native or dynamic, whether 4K and 60 fps operate simultaneously under all conditions, what the handheld-mode targets are, or whether loading times are measurably reduced. With release set for September 16 and file sizes marked as estimates, those details may still be updated.
