How to make a dramatic big finish?

you need to keep a buffer, recording all events that happen in the scene, so you can "replay" from 5 seconds ago. It can be quite a complicated system depending on how your game works, but there's really no other nice way of doing it.

how exactly would you get the buffer? is it a component or a script?

All you need is registered the Transform at a certain frequency. That is for instance, every 0.2s, you store them in order in an array and then you just replay the array in order with interpolation between each position and rotation.

$$anonymous$$aybe you could also have a camera set up to record the player in a "dramatic manner" then just display what the camera recorded for the player who died but in slow motion. Otherwise you'll need a buffer like Benproductions said.

Do you want to do a Slow-$$anonymous$$otion movements? Use: Time.timeScale = 0.3; If you has an animation, make it slowly.

This is a design/discussion question. There are multiple possible solutions, and within those solutions there are multiple implementations/technical questions. Unity Answers is designed for answering a single, specific technical issue per question. I suggest you post this question on the Unity Forums. The comments above outline the three approaches I see, all have their individual issues:

• Save the state on an ongoing basis. There nothing universal in Unity for this functionality. You would have to add this by recording things like position, rotation and any other properties that could change for each object.
  

• Record the screen on an ongoing basis. Play the movie back. There are both in-Unity solutions as well as platform-specific plugins. There are obvious performance implications.

• Detect when you are about to crash, and then slow down Time.timeScale for the last several seconds. Not quite what you asked for, but probably the most doable if you can figure out ahead of time you are about to die.

This question could have different solutions that derive into long discussions, and it might stay unanswered for an undeter$$anonymous$$ed amount of time. Please help us improve Unity Answers with concrete questions and answers, and consider using Unity Forums which is a great place to discuss ideas. Thanks for your comprehension, Unity Support.
