Con Artist! I hope you can make HERC scouting squads attack players base features to replace some of the zombies horde, when they attack us we can control our characters to shoot them and we can get some weapons, gears, medicals, some foods or waters or active gears for killing those squads. And sometimes we can encounter them on missions like on the streets or bridge maybe parks. Thank you~!
Others can contribute to this ideas too!
