This website contains some information on the various servant classes in the Fate series created by Type-Moon, more specifically the 'Extra' game series. In addition, there will be at least one example of each of the classes.
In addition to developing the game series 'Fate extra' they are also responsible for the creation of the animated series of Fate, based on their visual novel.
This video shows the trailor for the currently in development remake of 'Fate: Extra', the original combat-oriented game made by Type Moon. It was originally made for the PSP, and ported onto the PS Vita, before the remake was announced for 'current-generation consoles'.
