Time.timeScale is Having a Strange Effect on Physics

Hey all,

I am currently building a 2d physics-based game. I've built a moving character who can shoot bullets (which naturally travel much faster than the character).

Recently I've tried implementing slow-mo into the game by pressing space. The issue I'm having is that it seems to affect the physics-based objects in different and unexpected ways. The main issue is that the bullets become slower relative to the character - the lower the slow-mo timescale, the slower the bullet relative to the character. With a Time.timeScale as low as 0.1, the character can actually travel faster than the bullet and I have no idea why.

I have built a slow-mo script which fades in and out of slow mo by pressing the space bar. Relevant code:

 if (Input.GetKeyDown (timeSlow)) 
 {    
     slowOn = !slowOn;
 }
 
 Time.fixedDeltaTime = 0.02 * Time.timeScale;
 
 if(slowOn == true)
 {
     var pitchDown : float = gM.audio.pitch - (Time.deltaTime * pitchSpeedMultiplier);
         gM.audio.pitch = pitchDown;
         if(pitchDown <= slowPitch)
             {
                 gM.audio.pitch = slowPitch;
             }
     var slowDown : float = Time.timeScale - (Time.deltaTime);
     Time.timeScale = slowDown;
     if (slowDown <= reducedTimeScale)
         {
             Time.timeScale = reducedTimeScale;
         }
 }
 
 if(slowOn == false)
 {
     var pitchUp : float = gM.audio.pitch + (Time.deltaTime * pitchSpeedMultiplier);
     gM.audio.pitch = pitchUp;
     if(pitchUp >= normPitch)
         {
             gM.audio.pitch = normPitch;
         }
     var speedUp : float = Time.timeScale + (Time.deltaTime);
     Time.timeScale = speedUp;
     if (speedUp >= standardTimeScale)
         {
             Time.timeScale = standardTimeScale;
         }
 }    

Here is some of the relevant code from my bullet shooting script:

 //missile variables
 var missileFireRate : float = 0.5;
 private var missileNextShot : float = 0.0;
 var missilePrefab : Transform;
 var missileForce = Vector2(200,200);
 
 ...
 
 if(Input.GetKey(fireWeapon) && SubControl.isShotEnabled == true)
     {
         if(primaryActive == true && missileActive == true)
             {
                 if(Time.time >= missileNextShot)    //Time.time is the time since frame has started
                     {
                         //Code generates Missile, and instantiates in the location of the Turret
                         var missileInstance = Instantiate(missilePrefab, Vector3(transform.position.x, GameObject.Find("Suber").transform.position.y, transform.position.z - 0.03), transform.rotation);
                         missileInstance.rigidbody2D.AddForce(Vector2.Scale(TurretRotation.difference, missileForce));
                         missileNextShot = Time.time + missileFireRate;
                     }
             }
 
 ...

If anyone has any idea what's going on I would really appreciate the help!! :)
