Pure logic puzzle game. Plays like portal, even the story seems inspired by it? Gameplay at a faster speed with a lot of content. Keep in mind there no gun play, its pure puzzles. Considering they remade this in unreal. This version on there own engine is better value. The art style they did in this suits there cyberpunk sci fi theme. Plus the gold version has a lot more levels . Graphically this game still holds up well considering its age.
