Dirk Valentine and the Fortress of Steam is a Flash-based game designed by Nitrome Limited. It was released on March 27, 2008. It is designed much like many other Nitrome games, and has 24 levels total. Controls The player is Dirk, the hero of late 19th century steampunk England, who is armed with a breakthrough device — the chain cannon, which can be fired at any moment with the click of the mouse. The cannon can create bridges to get across ditches and can destroy enemies. Bridges will only be made if you fire them from a special surface which is heavier than the other surface, and attaches to the same kind of surface. The arrow keys move Dirk in the corresponding direction. The down arrow key is used to drop through chains. The Baron's henchmen are scattered along the steam fortress. The airships and clouds in the background give the feeling that the player is high up in the sky. In March 2008, Dirk Valentine was #5 on the Top 5 Games on Nitrome, although has now sunk off the charts. See Also *List of Nitrome Limited games *Final Ninja series References/
