Type Echo: Zombie Survival
Zomnic Horde is a Wave-based PVE game mode
NPCs spawn as Echo, 2 per round to a max of 18, and hunt down the players.
Ocasionally Echo will take on additional forms, including Reaper and Roadhog, for extra challenge.
On top of that; the Zomnics can ressurect their teammates by killing players - the zombie takes the form of the player that was killed: If your Mercy dies, the zombies now have a Mercy. Good luck.
Includes server options for Survival Mode (during each wave players can only respawn after their team captures an objective point) although this is untested so far.
Most playable heroes have custom code for their zombies, more may be added later
