A demo for a video game i s a
demonstration of what the videogame will
be l ike. There are usually demos for games
which will soon come out and demos are
usually free.
Thi s image shows a demo version of a game.
Beta The beta version of a game is as close to perfect as
the company can make i t, but any bugs, glitches or
other i ssues discovered in beta testing will usually
be addressed before the game's official release.
http://www.techopedia.com/definition/27136/bet
a-test-gaming
The beta version of a video game is the
final s tage before production. Usually a
beta test of the game will be released so
that the community can test for bugs
which the developers can then patch
before release.
Thi s image shows the beta version of a game.
Alpha means an early version of a program or
application, that is most l ikely unstable, but i s
useful to show what the product will do

8#q=alpha+version+definition&spell=1
An alpha version of a video game is the
vers ion before the beta version; i t is
usually unstable and has a lot of bugs
however the game i s unfinished at this
s tage. Some games get released to the
community in alpha state so that the
developers can get feedback on their work.

A pre alpha version of a video game i s
where the developers have put together
the concept of the game and began to put
the work into the game. Pre alpha versions
of the ga me usually a ren’t re leased to the
community as they are highly unstable and
conta in a lot of bugs as the game is
nowhere near finished.

Next Car Game.
Gold In software and application development, a gold
vers ion i s the final stage of software development
and follows the alpha and beta testing cycles
of software development.

n.html
A gold version of a game is the final version
of the game and is when most games are
released. He gold version of a game comes
after the beta version and there should be
less bug in it as the beta version is a release
for finding bugs before actual release.
Thi s shows the final release cover of GTA V.
Debug Identify and remove errors from (computer
