Blockader

Enter the Alien Battle

Blockader is a fast-paced sci-fi arena shooter built around enemy waves, automatic attacks, and skill upgrades. Players guide a cosmic defender through busy fights, collect useful resources, and try to stay alive as the number of aliens grows. The game is available to play directly in the browser, so it is easy to start a run without a complicated setup. The platform checks basic playability and performance to help provide a smooth experience on compatible devices.

Learn the Run

The goal is to survive waves of enemies while building a stronger set of skills. Your attacks fire automatically, so movement becomes an important part of each fight. Keep away from large groups, collect dropped resources, and choose upgrades that match the way you want to play. Some abilities add lightning strikes, poison effects, piercing attacks, or extra combat support. Resources such as Stars, Alien DNA, and Nano Components can also help improve future runs through permanent upgrades.

Controls

• Move: WASD or Arrow Keys

• Aim: Move the mouse cursor

• Attack: Automatic shooting

• Choose upgrades: Left-click

Playing Experience

Gameplay Feel

Movement feels simple and responsive, while automatic attacks keep the focus on positioning and quick reactions. Early waves are easy to follow, but the arena can become crowded very quickly once stronger enemies start appearing.

Tips for Play

• Keep moving instead of standing in one spot.

• Leave room to escape when enemies close in.

• Look for upgrades that work well together.

• Pick up resources when the area is safe.

• Use permanent upgrades to improve later attempts.
