Sekiro: Shadows Die Twice

Split-screen setup. Tested in latest legit Steam version of the game.

This handler uses the Sekiro Online Multiplayer mod v2.05 by LukeYui: https://www.nexusmods.com/sekiro/mods/577 , no need to install it in your Steam game files, the handler includes it. All credit to LukeYui for its creation.

Let all instances load to the title screen before pressing any inputs. Get pass the tutorial/first boss in all instances then press F1 in your keyboard and enable the online items, then one player (host) can use the Cursed Emblem item in the menu to create a co-op session. To co-op the host has to use the overlay (Shift+Tab) to invite other players, pause in all instances to use the cursor correctly in the overlay if it gets stuck. For invasion, other players can use the Vengeful Spirit item, no invite needed. If the host player dies it will need to create a new session and invite again. Rest at an idol before summoning other players for better results, restart Nucleus and run the handler again if the in-game enemies freeze or are unkillable. Disable any external overlays (like msi after burner or the nvidia overlay) if the invite overlay is not showing in the game when you press Shift+Tab in an instance.

If you use keyboards/mice after all the instances have launched, resized and positioned correctly, press the END key once to lock the input for all instances to have their own working cursor, you need to left click each mouse to make the emulated cursors appear after locking the input. Press the END key again to unlock the input when you finish playing. You can also use CTRL+Q to close Nucleus and all its instances when the input is unlocked. You need to unlock the input to be able to use the invite overlay.

Make sure you are using the vanilla game because a lot of mods are not compatible with the Sekiro Online Multiplayer mod. Install the SekiroOnlineFont file inside NucleusCo-op\handlers\Sekiro Shadows Die Twice\ if you get weird text in-game.

If you want to fix stretching in split-screen you need to create custom resolutions in your AMD/Nvidia/Intel panel (for example for a 1920x1080 monitor add resolutions like: 960x1080, 960x540, 1920x540 etc.) so the game can see and use them, this is also required for kb/m instances to work correctly. Alt-tab to the Nucleus app window to improve fps, reduce in-game graphics settings to improve performance. Lower your monitor scale % or set it to 100% if the custom resolution fix is not working for you.
