YMMV: Labyrinth of Reflections
- Game Breaker - Leonid uses his Diver abilities in this manner to get through the Labyrinth of Death. Most people aim and fire their weapons the way they would do it in Real Life. Leonid breaks the illusion and uses the old mouse-and-keyboard to aim the crosshairs with much better precision.
- Older Than They Think - the first novel is often advertized as "Russian answer to Serial Experiments Lain and The Matrix". However, Lukyanenko's novel actually predates the two.
