About CastleStorm
CastleStorm is a 2D physics-based tower destruction game that combines real-time strategy, resource management and tower defense brawling. In a comical story, Sir Gareth leads his troops against the Vikings to recover a stolen gem and bring peace to the realm. You control battles in real time, using medieval artillery, ground troops and spells to attack and defend.
Story and environments
The campaign follows Sir Gareth through 12 environments. Each level has multiple objectives, each with its own reward. You can win by capturing the flag, destroying the enemy castle or completing another objective set for the level.
Build your castle
A castle construction editor lets you create custom castles for use in battle. Your construction choices determine which types of troops and resources are available during battles.
Fight with weapons and troops
Fire a ballista with weapons such as Morningstars, Apple Grenades, Homing Eagles and flying sheep. Deploy swordsmen, knights and donkey riders to protect your castle gates, and cast spells to hold the enemy at bay. As you power up, new weapons and troop classes become available.
Multiplayer modes
CastleStorm supports local and online multiplayer, including a split-screen 1 vs. 1 mode and two co-op modes:
- 1 vs. 1: Face an opponent in split-screen.
- Survival Co-op: Two players fight waves of enemies together. One controls the ballista while the other commands ground forces.
- Last Stand Co-op: Two players each control a hero and fight endless waves of enemies together.
