Swarm Siege | Play the best free HTML5 online games directly in your browser. Enjoy a huge collection of casual H5 mini games with no download and no installation required. Play anytime on mobile and desktop.

Description

Aim, fire, survive — defend your castle from endless bug swarms and giant bosses in this intense arcade shooter. Face off against massive waves of unique insects, unlock powerful upgrades for your defenses, and test your skills against epic giant bosses. How long can your castle hold out against the ultimate swarm siege?

Instructions

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.
