This has to be a bug… Unexpected symbol ‘}’ on lines 18 and 21.

using UnityEngine;
using System.Collections;

public class core : MonoBehaviour {
	
	public static float healthC;
	public Rigidbody rb;
	public float speed;
	
	void Start () {
		healthC = 100;
	}
	
	void Update () {
		if (healthC <= 0) {
			Destroy(gameObject);
		}
		if (Input.GetKey (KeyCode.W){
			rb.AddForce(Vector3.forward * speed * Time.deltaTime, ForceMode.Acceleration);
		}
		if (Input.GetKey (KeyCode.UpArrow){
			transform.Rotate(Vector3.up * speed * Time.deltaTime, Space.World);
		}
	}
}
