Swarm Siege tasks you with protecting a castle from insect attacks by combining accurate shooting, priority management, and the gradual reinforcement of your defenses. First, you target the attackers to limit the number approaching the fortress. Then, as the resistance continues, you unlock powerful upgrades to make your position more effective. These choices influence how you hold the line, as a better-suited defense can help you respond to pressure that has become too intense. The goal remains simple: prevent the enemies from overwhelming the castle and extend your survival. The situation changes when giant bosses enter the scene, posing a greater threat than ordinary enemies. You must then decide how to divide your attention between this major danger and the other creatures still present. Otherwise, you risk focusing on a single target while the siege tightens around your walls. The game therefore revolves around a series of quick decisions, balancing the elimination of immediate threats with investment in upgrades that can support your defense over time. A poor choice can give the assault the upper hand, but a responsive strategy allows you to hold back the invasion for longer. Have fun!
