Halo has been one of the most consistently popular video game series of all time, ever since the first game was released in 2000. There have been many games released in the first-person-shooter franchise since then, but a lot of fans are the most fond of the first three games in the series that were made by Bungie. This initial trilogy told a great, interwoven story, and allowed players to wreak havoc against The Covenant as Master Chief.
