How To move Terrain for a TopDown shooter game

Hello everyone ,
After i tried the unity tutorial for the top Down Space Shooter , now i am trying to replace the simple Background texture with a unity terrain.
My problem is how to transform this terrain along the Z axes to create the Scroll effect

Ps: i am new at this, and i assume it just simple lines like Image Scroller, can anyone help me please.

You could try putting the camera to look straight down on the character and use the “Smooth Follow” script that comes with unity.

Or you could create a script that uses X, Y, and Z to move the player around: Unity - Scripting API: Transform.Translate

B/c Terrains can often be so large, the idea is that they are static, you should move the camera. If you wish to use a 3D background as if it was a 2D scroll view, you are better off creating a 3D background asset in a 3rd party application. (3ds max, blender, maya) Then you can make it tillable and move it as if it was a 2d asset.
