After Quake one John Carmack and American McGee began work on Quake II. It was released in 1997 and featured cutting edge graphics and 3D acceleration. It took advantage of the latest hardware. Allthough it was not an exact sequel to Quake 1 it had a similiar feel. The big feature of Quake II that made it a hit was its Deathmatch mode and later added Capture the Flag modes.
It also spawned a pile of mods including Weapons Factory, Lithium, and Action Quake. The success of Quake IIs multiplayer led to the development of Quake III which was solely based around CTF and Deathmatch.
The opengl game engine was also a big success and was used by other developers in games such as Daikanta. When it was made available for free to the public small third party games where also released, LTKTBM (a standalone version of Action Quake), and Alien Arena which now is a mixture between the Quake 2 and 3 source codes.
nothing like loading up gamespy and playing a round of Quake 2
Counter-strike was created by a man named gooseman who was a big fan of action quake and action quake II and wanted to see it brought to half-life. Even though a very crappy version of Action Half-life was made, CS remained the true succesor. It plays as counter-terrorists vs. terrorists and generally the objectives play as recover the hostages or plant the bomb.
Lately though there has been an overwhelming amount of hackers in the game who destroy it. Allthough when you find a good server it can be a very enjoyable game.
I am gonna go play some Counter strike tonight why dont you bring your PC and well make a lan party out of it
