Gameobjects instantiating in the wrong position

I'm trying to instantiate a gameobject five times in a horizontal line in front of the player (sort of like a shotgun, but the bullets are on a horizontal line).

This is what I wrote so far:

 GameObject tempObj;
 tempObj = Instantiate (groundBulletPrefab) as GameObject;
 AoEPosition = new Vector3 (transform.position.x - 2.0f + (i*1),transform.position.y,transform.position.z);
 tempObj.transform.position = AoEPosition + cameraTransform.forward;
 Rigidbody projectile = tempObj.GetComponent<Rigidbody>();
 projectile.velocity = cameraTransform.forward * shootSpeed;

It works well when the player is in the starting position, but when I turn 90 degrees to the left or right the bullets get spawned in a straight line in front of the player and perpendicular to it.

I think the problem is in the AoEPosition Vector3, since I only change the x axis coordinates, but I don't know how to fix it.

Got any tips?

Thanks!
