Similar to the first Deus Ex there are several conspiracy theories underneath the main plotline for players to discover and dive deeper into or alternatively skim over the surface if more focused on raw gameplay. Players join the game as Alex D, a trainee in the Tarsus Academy after a huge terrorist attack destroys Chicago and leaves it predominately in ruins. Invisible War picks up the story over two decades after the events in the original game and sees players exploring a world further ravaged by war and economic turmoil. Opting for a Windows and Xbox release this time around Invisible War stays true to the series of offering diverse player choice in how they approach the game in general and individual missions within it. Deus Ex: Invisible War serves as a sequel to the original Deus Ex and follows the story of Alex D in a new world that is constantly at war.
