Stronghold: Crusader Extreme HD

Firefly Studios' Stronghold Crusader is the standalone expansion pack to the 2001 Stronghold. In Stronghold Crusader, the player can command either Crusaders or Arabs loyal to Saladin.

The four historic campaigns, which serve as training for different gameplay aspects, follow the first three Crusades, in which the player alternates between commanding Crusader and Arabian forces. New to the game are the desert environment, which holds fertile farming land only in small oases, and Arabian troops available from the Mercenary Post, which do not require weapon production, but are either cheap and only useful in numbers, or powerful but double the price of their European counterparts. Depending on the campaign and the player-set options, the Lord unit can either have a Crusader or an Arabian skin, which also reflects on the cursor (sword or saber).

Stronghold Crusader HD (versions 1.3 and newer) is a high definition version of the 2002 game FireFly Studios' Stronghold Crusader and its 2008 enhanced re-release Stronghold Crusader Extreme. It introduces high resolution support to the game and allows the player to zoom out and view the entire battlefield on a single screen. For owners of the original game, there is an official HD patch to upgrade that version, free of charge.
