About Echo Siege

A numbered horde is marching on your base and you are a single soldier. Run through the gates to grow your squad, then smash into the columns before they reach your walls.

When the base falls, it is not over. The next loop starts with your last run marching beside you, so every defeat adds another you to the fight.

Echo Siege is the game the Swarm Rescue series grew out of: the same gates and columns, in a cleaner, arcade style.

How to play

SteerDrag left or right, or use A and D or the arrow keys.
GrowPass through + and × gates to grow your squad; avoid − and ÷.
DefendHit a column with a bigger squad to wipe it out before it reaches the base.
LoopEach time the base falls, your last run joins you on the next loop.

Tips

  • Two columns need two runs. Let your first loop take one of them.
  • Three stars come from holding the base in fewer loops.
