Castle Attack 2 is the latest publicly available version of the Castle Attack series, and the first to use 3D graphics. It was released on December 22nd, 2004 to help promote the upcoming release of Stronghold 2 roughly 5 months later. Designed by Simon Bradbury with additional design and programming done by Phil Busuttil, with graphics from Jason Juta, while Castle Attack 2 is very similar to the original Castle Attack game, it was also very different, adding new graphics, gameplay, enemies and more.
Like in Castle Attack, the game starts the player off with 3 archers on 3 multi-height walls, which they use to fend off hordes of oncoming troops. However, rather than just having one engineer building their castle 5% at a time, they now start off with 3 engineers, building the castle 2% at a time. The player can make any of the archers engineers at any time, and vice versa, provided there is space on the walls to have another archer, the maximum being 3. The player still has their pot of burning oil as they did in Castle Attack, though it is now activated using Z. Along with this, they also have 2 more tactical aids. Using the X key, they player can launch a barrage of rocks from a mangonel, which destroy everything it lands on, about half way across the battlefield. If that doesn't do the trick, the player can roll burning logs across the battlefield using the C key, destroying absolutely everything in their path.
