Skygarden Siege

Skygarden Siege is a real-time strategy tower defense game developed by Ironclad Forge and released in 2023. The game is set in a floating archipelago where players defend a central crystal core from waves of airborne and ground-based enemies. The visual aesthetic combines steampunk machinery with bioluminescent flora. The game features a single-player campaign with 15 levels, a survival mode, and a cooperative multiplayer mode for up to four players. Each level presents a fixed path that enemies follow toward the core. Players construct defensive towers on designated platforms using resources gathered from defeated foes and periodic supply drops. The game includes five tower types: Cannon, Tesla, Frost, Sniper, and Support. Each tower can be upgraded twice, altering its damage type or area of effect. Enemy types range from basic infantry to shielded behemoths and fast-moving fliers.

Gameplay mechanics operate on a resource economy of scrap and energy. Scrap is used to build and upgrade towers; energy powers special abilities and tower overcharges. Players begin each wave with a set amount of both resources. Controls on PC use mouse and keyboard: left-click selects towers or the core; right-click places or sells towers. The number keys 1 through 5 select tower types for placement. The spacebar pauses the game for planning. The Q key activates a global energy burst that slows all enemies for three seconds. The E key triggers a targeted airstrike on a selected area, costing 50 energy. Tactical techniques include chokepoint clustering, where towers are concentrated at path bends to maximize damage overlap. Frost towers are placed first to slow enemies, followed by Cannons for area damage. Snipers target high-health enemies from a distance. Support towers boost adjacent tower fire rate by 15%. Energy management is critical: players should reserve 100 energy for emergency airstrikes during late waves. Cooperative play requires communication to assign tower roles per player.
