FPS Character look up

So I have a character that has an animation for walking and running but I want to make it look up and down. I don’t know if I have to make another animation for looking up and somehow make it active while it looks up.

Here is a picture for reference on how it is now:

If anyone can help with links or anything on how it should be done would be appreciated.

There are many ways on how to do this.
1.You could make animation for looking up and down
or
2.Use IK system (Inverse Kinematics)

I would recomend looking at Inverse Kinematics


With this you donˇt need to do any aditional animations, instead you will acces character armature bones through script and change its behaviour through it.Also this small tutorial might help you.
