I'm in the Research Lab in Mission 8 of Quake 2 and am required to make a couple of jumps off a transparent bridge to nearby ledges to push a couple of buttons that will deactivate the force fields that will allow me to proceed further. I've tried making these jumps many times and keep falling short. I've tried jumping diagonally but that doesn't help either. Is there any secret or special technique to making this type of jump in Quake 2? One of the walkthroughs mentions a "rocket jump" but doesn't elaborate any further. Any help is greatly appreciated.
