public void save()

{

PlayerPrefs.SetInt("Score",score);

PlayerPrefs.SetFloat("PlayerPosX", player.position.x);

PlayerPrefs.SetFloat("PlayerPosY", player.position.y);

PlayerPrefs.SetFloat("PlayerPosZ", player.position.z);

PlayerPrefs.SetFloat("EnemyPosX", enemy.position.x);

PlayerPrefs.SetFloat("EnemyPosY", enemy.position.y);

PlayerPrefs.SetFloat("EnemyPosZ", enemy.position.z);

PlayerPrefs.SetInt("SceneID", SceneManager.GetActiveScene().buildIndex);

PlayerPrefs.Save();

}

public void Load()

{

PlayerPrefs.GetInt("Score", 0);

PlayerPrefs.GetInt("SceneID", SceneManager.GetActiveScene().buildIndex);

player.position = new Vector3(PlayerPrefs.GetFloat("PlayerPosX"), PlayerPrefs.GetFloat("PlayerPosY"), PlayerPrefs.GetFloat("PlayerPosZ"));

enemy.position = new Vector3(PlayerPrefs.GetFloat("PlayerPosX"), PlayerPrefs.GetFloat("PlayerPosY"), PlayerPrefs.GetFloat("PlayerPosZ"));

Don't forget to call PlayerPrefs.Save(). I've definitely done that a few times.

For Finding multiple enemies, I hope you tagged them as "Enemy", or something similar to that, with that in mind:

(Oh, according to Unity you need to write an abstraction Layer to PlayerPrefs to save multiple so think about doing it as a peasant)

foreach(GameObject ObjectToSave in GameObject.FindGameObjectsWithTag("Enemy"))
{
StreamWriter sw = new StreamWriter(@"SaveFile.s");
sw.WriteLine(ObjectToSave.Name + " - " + ObjectToSave.transform.Location.X + " - " + ObjectToSave.transform.Location.Y +
" - " + ObjectToSave.transform.Location.Z + " - " + ObjectToSave.transform.Quaternion.eulerAngles);
}
sw.Close();

Add StreamReader to read the save file from main menu, lets say Line one to point the scene and set bool Load for instance for scene Main Controllers cript to know to read the rest of the file, then just do the same thing you did for saving only in reverse to return everything the way it was in the scene.

Or run it like XML file that is a lot more elegant.
