The living dead

Wolf wants us to assist Nazar's group, and says his group is around the Jupiter plant. On arriving, dialogue with Aaz will reveal that the group is in the facilities to the northeast of the map.
Upon reaching the small group, Nazar will ask us to assist with the waves of zombies approaching.
==Walkthrough==
The encounter may be cluttered and confusing at first due to waves of zombies approaching from several directions. The key element in this encounter is that Nazar, Masha, and Dasha are all completely invincible so there is no need to put yourself in harm's way.
Each wave will consist of about 20 or so regular zombies with special enemies mixed in.

==Notes==
* Try not to let the waves spawn in the small building connected to the tunnels. Nazar and his group tend to get stuck there in the bottleneck, and the game will drop to an unplayable framerate as countless zombie corpses pile up and collide with each other in the tunnels.
