Goldeneye 007 Tutorial: Surface 2 DLTK
Surface 2 is a great level to start with if you're a newbie since it's the easiest of all DLTK levels. Again, what makes the level easy is its lack of guards and enemy objects. The KF7 guard near the tower entry can be annoying though, and he might kill you on good runs.
Although typically the level would require the elimination of only one guard, to get the Comms Room key, the WR strategy skips this and does not shoot a single guard. The WR strategy is very similar to LTK.
