Halo 3
Halo 3 is a 2007 first-person shooter video game developed by Bungie for the Xbox 360 console. The third installment in the Halo franchise following Halo: Combat Evolved (2001) and Halo 2 (2004), the game's story centers on the interstellar war between 26th-century humanity, a collection of alien races known as the Covenant, and the alien parasite known as the Flood. The player assumes the role of the Master Chief, a cybernetically enhanced supersoldier, as he battles the Covenant and the Flood. In cooperative play, other human players assume the role of allied alien soldiers. The game features vehicles, weapons, and gameplay elements familiar and new to the series, as well as the addition of saved gameplay films, file sharing, and the Forge map editor—a utility which allows the player to perform modifications to multiplayer levels.

Where Halo 3 sits on the grid
The grid places every game in the catalogue on measured axes rather than on an opinion. This is where Halo 3 lands on each map it has the data for, with the share of the catalogue it beats on each axis.
- Year
- 70ahead of 22% of the catalogue
- Reach
- 63ahead of 97% of the catalogue
Percentiles are against the games that carry a reading on that axis, not the whole catalogue: counting a game with no figure as a zero would flatter everything that has one. How the grid works.
What readers say about Halo 3
Reviews written by people who have played it. These are separate from the GamingPickz Score and are never averaged into it: that score comes from thousands of Steam reviews with a sample-size correction, and a handful of unverified ratings would distort it rather than improve it.
