When someone is given a last chance, it means that they have one final opportunity to do something or correct a mistake. However, if time is running out and it truly is the "last chance," then it may be described as the "final chance," the "ultimate opportunity," the "closing window," or the "final shot." Other synonyms for "more last chance" could include "final attempt," "last-ditch effort," "final opportunity," or "one last try." No matter what terms are used, the message remains the same: this is the very last chance to make things right, and one must take advantage of it before it's too late.
