Echo Loop

Defend the Core, then watch your run play back, every wave you clear becomes a translucent Echo that fights beside you forever.

How to play

You are the defense. Move around the Core and auto-fire at the enemies pouring in each wave. Clear a wave and your run is recorded, keep it as an Echo and a ghost of your past self will replay those exact moves in every wave that follows. Stack up to six Echoes and a whole squad of former selves fights alongside you while you focus on the new threats.
