Shooting bullets in different patterns

Hello, so I am coding this space shooter game and I am creating different weapons.

What I stumbled across is when I want my bullets to shot within rotated path I just cant make it work - I am just rotating the bullet prefab, not the path itself...

Check the screen - I am shooting in red line, but I want bullets to go like the blue lines.

My code for shooting straight:

public void Shoot() { GameObject bulletHolder = GameObject.Find("BulletHolder"); //find the bullet holder in stage

     if (redWeapon == true)
     {
         GameObject bullet01 = (GameObject.Instantiate(PlayerBulletGO));
     bullet01.transform.SetParent(bulletHolder.transform, false);
     bullet01.transform.position = bulletPosition01.transform.position;
     
         if (redWeaponLvl >= 1)
         {
     GameObject bullet02 = (GameObject.Instantiate(PlayerBulletGO));
     bullet02.transform.SetParent(bulletHolder.transform, false);
     bullet02.transform.position = bulletPosition02.transform.position;
         }

And bullets move script:

    void Update () 
 {
     //bullets current pos
     Vector2 position = transform.position;

     //calculate new pos
     if(gameManager.GetComponent<GameManager>().movingFromRight == false)
     {
     position = new Vector2 (position.x, position.y + speed * Time.deltaTime);
     }
     else
     position = new Vector2 (position.x + speed * Time.deltaTime, position.y);

     transform.position = position;

     Vector2 max = Camera.main.ViewportToWorldPoint (new Vector2 (1, 1));

     if (transform.position.y > max.y || transform.position.x > max.x + 10f) 
     {
         Destroy(gameObject);
     }

 }
   

Where to go from there?

Thanks people!
