Hello welcome to a guide to the most straightfoward alternate ending that is obviously not canon but I heard there is a mod related to this so here's how to do it

When Gman Opens the portal at the end of his speech litreally stand still, ignore the threats of this unknown entity that pulled you out of hell and teleported you left and right while giving his speech and stand still until he loses his patience

No Im serious stand still until Gman loses his patience and you got the ending

Thanks for Reading
