Stronghold: Crusader is the successor to Firefly Studios's 2001 game
Stronghold.
Crusader has much in common with the original Stronghold, but differs
from its predecessor in the fact that the game is no longer set in a
pseudo-Europe, instead being set in the Middle East during the Crusades. The game features a multitude of new Arabian
units that can be purchased in a new building, the mercenary post.
Though the Arabian troops do not require any resources to produce, they
are rather expensive. The game was also released as Stronghold Warchest.
This version was a compendium of Stronghold and an enhanced version of
Stronghold: Crusader, containing additional characters and an additional
Crusader Trail.
Stronghold Warchest was only released in limited number of countries
(i. e. USA or Poland), meaning players in the rest of the world have
never encountered the second Crusader Trail, or second set of
characters. This changed when an updated version of Stronghold Crusader,
Stronghold: Crusader Extreme was released in early 2008.
