Sierra and Lucid Games has announced that the pre-order bonus content will vary depending on the platform for the upcoming Geometry Wars 3: Dimensions. The Secret Eye level is a uniquely shaped level in the form of a triangle with an evolving red cube in the inside to complicate matters. Blood Count on the other hand features a torus shaped gird.
If you pre-order on the PlayStation 4 or PS3 version of the game you will receive the Secret Eye level, while Xbox owners will receive Blood Count. Pre-ordering the game through Steam however will get you both of the pre-order levels. Outside of these pre-order bonus levels, Xbox and PlayStation platforms will each have an exclusive level.
