The main problem with that is that it makes it very easy to empty a POI to loot it without risk.
Agreed that is the first thing that came to mind. Was getting ready to post this thought.
I can't remember if it was a small mod or a standard function of the game.
It was inspired by world war-z. It would be more visceral now with the
Zombie stumble and fall animations. Especially if a lot of the volume were
coming from elevated areas.
It would have to be a really well planned event though, in order to stay
withing present spawning constraints. 1 The parameters 30 zombies maxalive,
following the hordenight rule. 2 It would need new spawner volume types
that are activated by the event. 3 Must be regulated to not exceed todays
limits or console version would fail. 4 Pooling might be a possible mechanic.
1 30 Zombie Maxalive could be regulated by Biome spawner.
2 New spawner volume type, would be biome spawner controlled, placed in pois
near easier exit points in pois. If not two things will happen. People will
just make noise to kite POI sleepers away, then walk in and loot. After the
onslaught pois would be drained of sleepers making it way easier to pillage.
If these are placed at say a window or behind a broken wall, they are out of
sight so they fit in the spawning parameters, and add to a visual interactivity
with the environment. They would leave poi sleeper volumes intact for normal
engagement. The spawn locations could be controlled by tags, on specific blocks.
3 Volumetric spawn needs regulation, for console and pc. Or it would not be
considered.
4 Pooling to present a continuing spawning mass, without taxing hardware. Plus
it would not interfere with the rest of the assets and events.
