Game.Description =
  "IMPORTANT: This handler uses the Sekiro Online multiplayer mod v2.05 by LukeYui. 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 an online session. To co-op the host has to use the golderg overlay (Shift+Tab) to invite other players, pause in all instances to use the cursor correctly in the overlay otherwise it can get 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. 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 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. 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. Restart the instances if the in-game enemies freeze. Alt-tab to the Nucleus app window to improve fps, reduce in-game graphics settings to improve performance.";
