About Swarm Siege

In Swarm Siege, you take on the role of the last line of defense against relentless waves of insect attackers targeting your castle. This arcade shooter challenges you to aim and fire a constantly shooting turret that you control with the mouse or touch input. Each wave grows more intense, introducing new types of bugs and progressively tougher giant bosses every few waves. As you survive, you earn upgrades that improve your turret’s firepower and defensive capabilities, helping you withstand the increasing assault.

Strategic positioning of your turret’s aim is crucial since it continuously fires in the direction you choose. You can also collect supply crates dropped by defeated enemies, which provide temporary boosts like rapid fire or freeze effects. Combining two crates creates more powerful bonuses, adding another layer of tactical depth. If bugs breach the walls, your castle takes damage, so staying ahead is essential.

Between waves, you can spend coins earned during gameplay to repair and strengthen your castle’s defenses. Swarm Siege mixes fast-paced action with tower defense elements, requiring both quick reflexes and smart use of resources. The game offers a straightforward yet challenging experience as you test how long you can protect your stronghold from the never-ending onslaught. Fans of 2D shooting and defense games will find plenty to enjoy in this action-packed, bug-swatting survival challenge.

How to Play

Bugs are attacking your castle and you are the last turret standing. Aim with your mouse on desktop or drag on the screen on mobile - the turret fires nonstop in that direction, so position your shots wisely. Survive endless waves: every wave you survive upgrades your turret, and a giant boss arrives every 5th wave. Grab falling supply crates to gain bonuses - Rapid Fire, Cannon, Triple Shot and Freeze - and drag two crates together to combine them into a stronger mega bonus. Bugs that reach the wall damage your castle, so stop them before they arrive. Repair the castle with coins between waves, climb the local top 10 leaderboard, and hold the line as long as you can.
