Returnal Update 3.002 Patch Notes
- Bug fixes
- Stability Improvements
We are still waiting on the official detailed patch notes for the game but that’s the gist of this hotfix for now.
If you still don’t know how to access the new content, here’s some information that is taken from the official FAQ.
How do I access the Tower of Sisyphus?
To access the Tower of Sisyphus, you need the hookshot. To acquire the hookshot you need to beat the second boss, Ixion, found in the Crimson Wastes. When beaten, the boss drops the hookshot.
Then return to the start of Overgrown Ruins where Helios is located. In the starting area there is now a ledge you can access by using the hookshot.
How do I initiate co-op?
To initiate co-op, approach the portal, Chronosis, at the start of a biome (for example there’s a portal in the starting area, where Helios is located). From there, you can choose to host a public cycle, where anyone can join your session, a private cycle, where only someone with an invite will be able to join your session, or join a cycle and enter another player’s session.
If you are the host of a session, you will be able to gain permanent equipment, but you won’t be able to increase your Scout Rank. When ending a session, the host keeps their progress. If you are the joining player, you will be able to increase your Scout Rank, but unable to gain any permanent equipment. A joining player cannot access their permanent equipment which the host has not yet acquired. If you join a game, after the session is done, you will be returned back to the start of your cycle.
