Which are the tutorials that can be done on the current Unity?

I was willing to do the space shooter tutorial. But in the description, it said that it was made in Unity 4 and only checked for Unity 5.1. How to know that all the tutorials are able to be done at the current updated Unity?

Are you referring to this?:

If you are then you can find the tutorial here:

Even though it was made from Unity 4 and just updated it for the compatibility on Unity 5, it would still worth follow the tutorial. The scripting are not that much different after all.
