Broken Helix

Broken Helix is a third-person shooter game developed and published by Konami for the PlayStation in 1997. It was marketed as featuring "4-D" gameplay, referencing the fact that the game's events all unfold in real time (time is sometimes referred to as the fourth dimension). This allows the player to activate and deactivate certain objects in later levels of the game. It also has four plot lines, allowing the player to finish the game in four different ways.
