About CastleStorm
CastleStorm blends 2D physics‑based destruction with tower‑defense brawler action, letting players build medieval forts and smash them in real time. The premise draws on a childhood love of LEGO‑style castles and pits knights against Vikings across twelve distinct environments.
Beyond a story‑driven solo campaign, the title offers a custom castle editor, split‑screen and online multiplayer, and two co‑op modes where players share control of artillery and ground troops. Full controller support and a suite of Steam services round out the experience.
01 / THE GUIDE
Story Campaign
The solo campaign follows Sir Gareth as he battles Vikings to recover a stolen gem and restore peace. Each level presents multiple objectives—such as capturing a flag, destroying the enemy castle, or completing a predetermined task—each with its own reward.
The narrative is described as comical, and the twelve environments provide visual variety throughout the campaign.
- Observe which objective appears first; it often signals the most direct win condition.
- Try alternate objectives in the same level to compare the different rewards offered.

Castle Construction Editor
Players can design custom castles using the built‑in editor, selecting which troop types and resources will be available during battle. The editor’s layout directly determines defensive and offensive options for each match.
Because the editor decides which units and weapons can be deployed, strategic placement of towers and gates is essential for effective defense and resource management.
- Balance defensive towers with openings for ground troops to keep both firepower and mobility.
- Experiment with different layouts to discover which configurations suit your preferred tactics.

Multiplayer and Co‑op Modes
The game supports local split‑screen and online play. In 1 vs 1 split‑screen, two opponents battle directly, while co‑op modes let two players team up against waves of enemies.
Survival Co‑op assigns one player to the ballista and the other to ground forces; Last Stand Co‑op has both players controlling heroes against endless enemy waves.
- Coordinate roles in co‑op—one focusing on artillery while the other manages troops—to cover more ground.
- Practice split‑screen locally to fine‑tune timing before attempting online matches.

Arsenal and Spells
Players wield a medieval ballista and launch a range of explosive projectiles, including Morningstars, Apple Grenades, Homing Eagles, and even flying sheep. Ground forces such as swordsmen, knights, and donkey riders defend the castle gates.
Spells are also available, providing powerful effects that can turn the tide when conventional weapons are insufficient.
- Mix projectile types to handle different enemy formations—explosives for clusters, homing eagles for single targets.
- Reserve spells for moments when enemy pressure overwhelms your ground troops.

Steam Features and Platform
CastleStorm runs on Windows and integrates Steam achievements, trading cards, cloud saves, leaderboards, Remote Play on TV, Remote Play Together, and Family Sharing. Full controller support is listed among its features.
