Well make that max zombies and you have a problem.
I assume you meant max horde night zombies.
If max zombies is too difficult for someone he shouldn't turn on max zombies but a lesser setting. There is already a setting in the game that is called "Insane" and there are people who won't survive 10 minutes playing it. Do those people really set the game to insane nevertheless and then complain they have a problem?
And wouldn't it be nice if there were an overall setting nobody could survive and one everyone could survive so that everyone could find a challenging setting inbetween?
At the moment there seem to be players who are too good (or maybe too cheesy) so that the game is too easy for them in any setting.
If you wanted to set max zombies in a game with my proposed change I would advise to turning horde night zombie speed down accordingly. This might prove an interesting game for Alpha16-lovers.
Also one demolisher that explodes could get your base wrecked way faster.
Who says demo explosions have to increase likewise? In XML this is already a separate setting from his hand damage.
It also does a lot more to people who do melee as they kill Z´s way slower.
SP players who melee might need stronger side walls, more redundancy and/or more turrets, I agree. Depending on how they fare at the moment and whether the feature would be on in all difficulties and whether initial damage of zombies was decreased or not they might need to turn down difficulty, or adapt their design.
Maybe you are overestimating the results of such a feature even for a melee base though. I have played what I assume to be a melee base as single player in A19. And there were always times where I could or even had to go on top of the base and take a look around. I did eliminate stragglers hitting on walls at that time.
Also I'm not sure if zombies stay in destruction mode for hours on end. Don't they retarget sometimes so they eventually appear in front of the club of the player?
And sure changes can go either way. But making it harder for people who don´t cheese, in order to prevent cheesing is the wrong way imo.
Well, difficulty doesn't need to change for the average case if initial damage to blocks is reduced to compensate for the higher damage of some of the zombies.
This feature could be an option you can turn off again, or preferably a setting that only starts to work at higher difficulties. And it should be something that can be changed in xml, anyway.
I am a player who uses POIs for bases. I not only use POIs from the first day in a new game, I also use them as a base for my end-game horde base most of the time. I get new challenges that way fitting my idea into a pre-existing building. Since I have to compromise some things, it often makes it more challenging in the end than a fully self-made base. And I have a different horde base every time even when I use the same ideas as a previous base.
I would like a mode like this as well. I always build emergency exits, secondary holding postings, they rarely get used now. If I simply increase block damage I know they will almost always breach through the front where I fight them, possibly with this mode they would have surprises for me more often. Who knows?
