Quake 2
The greatest game in the World ever... Part 2

Quake is essentially a multiplayer game with added single-player functionality. When id created Quake 2, it went all-out to create a 
strong single-player 
experience, but 
remembered to cater for 
the hardcore deathmatch 
fans as well. The result is a 
multiplayer game that bares 
some resemblance to Quake, 
but is also refreshingly 
different. Quake 2 is the 
slower game, with a finer 
weapon balance that lends it more of a strategic edge than its predecessor.
