About Swarm Siege: Defend Your Castle from Endless Bug Waves
Swarm Siege puts you in command of a single turret standing between a relentless insect army and your castle walls. The premise is direct: aim, fire, and survive for as long as possible against escalating swarms of unique bugs and epic giant bosses. Several scenes show small, dark-shelled creatures with bright red, green, or purple eyes advancing across the battlefield. The ground beneath them displays a warm, orange-toned cracked earth surface with irregular, interlocking polygonal patterns visible across multiple views.
How to Play Swarm Siege: Survive Waves, Grab Crates, Hold the Line
The bugs are already at the gates and your turret never stops firing — it shoots continuously in whatever direction you aim, so where you point matters. Bugs that reach the wall deal damage to your castle, so the priority is stopping them before they arrive.
