Videogames were changed forever when Bungie released Halo: Combat Evolved in 2001. In that seminal release, the world met Spartan II cyborg Master Chief as he is awakened from cryo sleep to fight against the alien Covenant. We also met Cortana, the AI that would accompany Chief and become the voice in his ear as he fights. Among many of its revolutionary ideas was its holy trinity of combat that mapped guns, grenades and melee onto an intuitive control scheme that provided a deep and flexible options and allowed players access to large maps and vehicles. As the series progressed, it implemented a suite of online features and pared down gameplay into tighter design. At the end of Halo 3, Master Chief re-entered cryo sleep aboard the UNSC’s Forward Unto Dawn as it drifts aimlessly through space with Cortana watching over him. The trilogy complete, Bungie flexed their creative muscles on Halo 3: ODST and Halo: Reach, two games that would expand the structure with new modes and matchmaking options.
