Semicircle Interception

NOTICE: If you experience lag while playing, try lowering the quality in the options and/or switching away from the chat tab when playing a wave. Cheers! Let me know if you experience any strange behaviour with the game.

As the Semicircles approach your base, intercept them as they line up with your Receptor circles by pressing the corresponding key of that Receptor circle. You will lose health if you fail to intercept a semicircle or mistakenly trigger a Receptor.

Default keys are A, S, K, L for the Receptor triggers and ESC to abort the current wave. These can be changed to any alphanumerical, arrow or NumPad key within the options.
