The obvious sequel to
Lode Runner, designed by Presage, and released in 1998 by GT Interactive.
LR2 follows the spirit of the original Lode Runner with devilishly hard puzzles and great gameplay.
Where Lode Runner was a side-view, single-screen game, LR2 uses an isometric view and most levels requiring scrolling.
If I had a better joystick, I'd never get online.
