First they never ventured forward unless inside the zone covered and protected by my shield. I didn't know if those outside got killed, or they just got a gut feeling to evade such imminent death. In the end they just came from the part covered by my shield.
And that wasn't all! First the aquatic monsters came first, forming some sort of a flesh bridge for other ground forces to walk over their backs to that damn monster.
It was really a remarkable scene, one I never expected. And it was pleasant to see. Also my flying monsters came and kept their flying zone inside my shield.
Great! Now my main army was here, it was time to give this damn bastard a true taste of what hell looked like.
