Camera movement according to rotation and actual position RTS

Hi guys i'm doing and RTS TD game. My camera can rotate all around the field. My camera has a rotation on X of 65 degrees from start; the player can see the whole field from that view. Since my player can rotate at will, i want to let him move up, down, left and right after he rotated, and my plan is to keep W A S D keys to move up, left, down from the new point of view. My issue is W and S in Space.World won't let the player move after rotating his camera (it ignores his actual rotatio), so i tried using Space.Self and Vector3.forward, Vector3.up and Vector3.back, Vector3.down but all of them won't have the results i want, because .forward and .back makes the player zoom in and out respectively. And .up and .down actually kinda work, but they make the player zoom in and out too.

So any ideas to let the player keep his WASD movement after used the rotatios feature?

Right now i letft W and S on Space.World, so i can move around without rotation. And A and D can move perfectly before and after rotating.
