Garry's Mod
What is Gmod? : Garry's Mod is a sandbox physics game using a modified Source engine, created by Garry Newman.
Garry's Mod has been available on Valve's content delivery service, Steam, since November 29, 2006.Purchase of
Garry's Mod requires the user to own at least one game on Steam based on the Source engine, such as
Half-Life 2,
Counter-Strike: Source,
Portal, or
Team Fortress 2. It is also commonly used for the creation and publishing of videos
on YouTube, mainly from
Team Fortress 2,
Half-Life 2,
Portal,
Left 4 Dead and
Left 4 Dead 2. Garry's Mod was originally a modification for Valve's
Half-Life 2, but was later made into a standalone Steam game that was officially released on November 29, 2006 dubbed
Garry's Mod 10. The current version,
Garry's Mod 13, was released October 24, 2012. In March 2013 it was revealed that the game has made over 22 million dollars. As of November 2013 the game has sold 3.5 million copies.
Multiplayer : Garry's Mod supports
multiplayer
gameplay on dedicated game servers. These servers are operated by the
community and some servers earn a profit from having additional VIP features. Players can build contraptions together and communicate via text or voice.
Garry's Mod servers run many game modes, most of which are
user-created modifications. Some of the more popular modes include:
Roleplay (RP) where players take on a specific role in the server's
society, where players role-play in a city-like society and
Trouble in Terrorist Town (TTT),
which involves a group of terrorists (Innocents) (this can also include
a group of detectives, who have special tools aid in finding traitors)
with another, smaller group of traitors within them, whose goal is to
kill all of the Innocents; as well as several zombie survival mods.
There are also
Deathrun servers where the "Death" players trigger traps
to try and kill the other players that are trying to get to the end of
the level, which is usually an obstacle course, of sorts.
Comment : I will rate it with 7 for Co-op and multiplayer cause you can play full of mods and maps.
I really like the horror Co-op maps and gamemods.
