Super vultures have always felt archaic to me. They feel like a heavyhanded way of discouraging players to use vehicles on horde night.
To my knowledge, there is nothing in the way of information on these guys in the game. There is no warning, no tells. A new player could get a vehicle and think about using it to evade the zombies for a time, or just get away from a bad situation, and suddenly they're swarmed by vultures that move faster than their vehicle, and quickly overwhelm them with status effects. I don't believe there is a journal entry nor a ingame explanation for these guys.
This sudden attack feels unfair to new players from what I've seen, and to me, too. They immediately attack you moments after getting into a vehicle, and can cause satus effects through the vehicle. It just tells you "Yeah no, you can't do this, go defend a poi or something". Veteran players just kind of know that you cant interact with your vehicles during a horde at all. I think most people are just used to this, so they don't even try using vehicles during horde nights.
However, there is nothing wrong with the idea of using vehicles as a temporary getaway, or transporation, or even to kill a few zombies. I'll share a overhaul I came up with that might alleviate this problem somewhat. This is just an idea, though.
Allow players to use vehicles without any restrictions, and remove super vultures, but cause gas to drain significantly faster during horde night, promoting using them scarcely as an escape tool. A full tank might last around a minute or two. This could be coupled with a time to refuel. Make it so that it takes a few seconds to refuel, (depending on how empty the tank is) to add some risk. This could even be modified with grease monkey. I think this would be the best balance between fun and gameplay balance. This could be explained away as something to do with the blood moon affecting vehicles. You can even mention it in a journal entry for visibility, and add some text that appears when a player enters a vehicle during a horde, informing them that something is wrong with their vehicle. The high gas cost would also add a resource cost to it, making it something you cannot do consistently without significant preparation.
You could even make zombies target vehicles more. As it stands, they don't seem to go out of their way to destroy lone vehicles, going straight for the player. Make it so that players have to invest in a protected place for their vehicles, or the zombies would quickly swarm and destroy them if nearby/unprotected. If a player opts to not use vehicles, they'd have to keep them a distance away during horde nights. This would add a barrier of entry to this strategy, and could also cause tense moments where the player has to use limited fuel to save their vehicle from being destroyed, or somehow get in while the zombies are attacking it to escape a dire situation.
I think this would be hard to implement, but would definitely be a complete overhaul to what we have now, and a lot more fun, in my opinion. It would add gameplay variety to horde nights, which I think would be a major plus.
What do you think, is this a terrible idea? It very well could be. I've made a poll asking about if you think super vultures should be reworked into something else or not. Let me know what you think. I didn't make this to bash on the current system, but to explore potential evolutions and changes to make it better.
