Particle shield
The counterpart to the particle cannon: the shield absorbs enemy particle beams before they hit your defense.

The Particle shield protects your defense units against attacks by a Particle cannon. Every level expands its particle storage by 30,000. It requires Particle analyzer at level 2 and your Spice mine at level 6.
When a particle beam hits your planet, it first uses up the particles in your shield. Only what's left after that reaches your defense. So what counts is how full the shield is – an empty shield protects nothing.
Like the cannon, it's charged with surplus energy. On the Economy page you can make the shield the first storage to charge, so it's back to full quickly after a hit.
Background
The particle shield is the only stationary facility that can absorb the attacks of a particle cannon. The success depends on its level. The shield can store a maximum load of 30,000 particles per level and is able to resist the same attack power. To be able to defend major particle attacks a sufficient expansion level and an adequate energy supply has to be established.
