EDIT: On their Twitter page, they said that: The Iron Wall Gun spawn Iron Wall Units... So the Base can spam things by itself. It will evolve when we waste enough resources on it. The shield cannon is the iron wall gun. basically it spawns a standing still shield unit right in front of closest enemy unit (enemy base if no enemy on field). If there is zombie still diving underground, the shield will spawn above it AND THE ZOMBIE MOVES THRU IT!! *Cyka!!*

This shield unit has metal attribute and low health, about 2HP / upgrade level (20 HP at max level 10), not affected by base cannon power level.

As with other metal units = It will not defend units behind it againts area attacks and shockwaves. So it effectives againt those hurricanes, capable of making them standing still if you have quick cannon. But very weak againts mass numbers of squirrels (which usually you would zap with a single normal beam cannon)
