-LZ already does get Zombie Soldiers as siege from the top, about every 5 seconds. From the bottom spawn webbers and titans.
-BC Beast is meh... Just like in LZ Titans and webbers spawn on right and bottom left side. He'd have to remove them all and replace them for a "Mini-beast" which basically has half hp of a normal beast and only spawns one time on the bottom left side. Nuke and Fire proof and can not take more than 50 dmg per shot. Or something like that...
Sounds weak but combined with a horde it's a target it must be prioritized. Dangers of getting overrun still remains.
-Zombie Officers (?) support the Zombies? Nests and watchers already have a big aggro radius that send their hordes against nearby players. If mc is dead, zombies get the sentinent nest effect.
I don't see how a "zombie supporter" can come in useful.
-Zombie Flamer could be nice, but then we'd need some kind of counter for that. We don't have a flame-resistent armor. A new equipment to take could be created. Can be used to remove flame effects on you or an ally (survivors included) next to you and have a temporare immunity of being burned again for (like) 10s. Cooldown could be 60s and have up to 3 charges.
-Core punishment is a difficullt thing to talk about. Yes, there are people who don't give much of an F about it, but there are also people who don't like the "Lights out" effect. An additional rare enemy is more punishable for those that ignore the core, but for those that already don't like the "lights out" effect? They get punished even further.
I remember back in 2015 when the Agent was op... Rest in supplies, my friend.
