Halo 2
multiplayer levels should follow the Halo universe from a design and
aesthetics perspective. Multiplayer levels borrow geometry or
architectural elements from single-player environments; however,
multiplayer levels tend to be removed from the narrative portion of
the Halo universe. This
allows a Halo 2
multiplayer level to look and feel like Halo while offering the designer
more freedom.

Human structures, ships, vehicles, weapons, and other
elements are based on a military theme. The Human technology style
is relatively near-future with obvious advanced technology that is
recognizable and functional without being overly complex. The color
palette reflects the military theme: dark greens, olive, gun metal,
burnished aluminum, dark gray, black, and brown. Human construction
style tends to be angular with 30- and 45-degree angles being
standard.
·
Covenant structures, vehicles, ships, weapons, and other
elements are based on a science-fiction theme. Covenant technology
is more advanced than comparative Human technology but less
advanced than Forerunner technology. The Covenant color palette is
metallic red, blues, and purples. These same colors are also found
on their energy fields, shields, and other luminous elements.
Covenant construction style tends to be organic and features smooth
curves and rounded surfaces.
·
Forerunner structures, such as the Halo ring, and the technology they
contain are far more advanced than Human or Covenant technology.
These structures tend to be massive and distinctly alien. External
Forerunner structures tend to have smooth metallic surfaces with
large, bold architectural features. Interior structures tend to be
open and reminiscent of a cathedral. Common interior elements, such
as pillars, illuminated control panels, wall panels, and various
alien machinations, are the hallmark of Forerunner construction.
The Forerunner color palette consists of metallic colors such as
silver. Blues, purples, and yellows are commonly found on the
luminous elements of Forerunner construction.

The inner surface of the Halo ring and its terrain mirror
the environments found on Earth, with the exception of geological
formations or features related to geothermal or volcanic activity
such as geysers or volcanoes. These environments include rolling
plains and grasslands, deserts, oceans, lakes, beaches, islands,
forests, snow, and ice-covered canyons.
