Intelligence reported that the enemy was about to attack in Crowd Evolution 3D. Moreover, he chose a direction that was completely unprotected. It is necessary to deliver fighters there as quickly as possible and organize defense. On the way to the positions, you need to collect as many reinforcements as possible, passing through the green gate. Some enemy groups have already managed to infiltrate the rear, so be prepared to meet them and deal with them on the run. Before each attack you need to select upgrades. Having reached the positions, set up defensive structures and do not let the enemy break through in Crowd Evolution 3D.
