The study of Halo, either Halo
1,
2, or the upcoming Halo 3 and Halo Wars. These games for
Xbox and Xbox 360 were developed by Bungie, and with some
help from Microsoft. This intellectual pursuit embodies all the aspects of Halo such as: different combat strategies, stealth fighting, grenading, timing, sniping, up-close combat, teamwork, aiming, psychological training, nerves-of-steel, using vehicles and
air transportation, and anything else related to improving one's Halo skills.
