Zombies will not spawn inside your safe-house. I assumed that people would understand this. The game keeps persistent zombie locations (I believe they wander through a set territory). This is the only place they will not spawn at the games outset. However if they track you through sight or smell (and they are very good at that now) they will smash their way inside and then you're in a world of pain.
Also a human in perfect condition (not starving, not dehydrated, not in pain, not encumbered badly) will just barely outpace the zombies 99% of the time and I do mean JUST barely (although because of the varied speed you might take a hit or two if you're careless, once you see the zombies you should already be running, not 'just getting that last garden hose or can of tinned peaches'... RUNNING FOR YOUR LIFE), however because there are so many it's very easy to get trapped and boxed in. Staying in tip top shape is more important than ever before and the use of speed/stamina enhancing pills is more important than ever before (aka - caffeine pills, etc).
This is the apocalypse... You are not meant to survive... If you somehow manage to it should be through sheer determination, skill and strategy, not dumb luck or exploits like repeatedly smashing zombies through windows .
You can play the 'on the move' game but just don't be expecting to be able to lug around 100kilos of equipment and the kitchen sink to boot and dance circles around the zombies... Eventually the zombies will catch you... If zombie movies have taught me anything it's that you can't outpace the undead ... This mods not being made for just anyone... It'll sort the boys from the men .
That was just a brilliant post.
To be honest, your mod is not my cup of tea. I generally dislike when authors put everything against the player in nearly-sadistic ways (the result is usually less "artistic", IMO).
The game is fairly hard as it is now. Even if you hoard and munchkin your way around, you are never entirely safe (or at least I didn't find any invincible combo that doesn't require absurd stats or cheating). But it's also lenient on how we play, giving a wide array of strategies, and emergent gameplay.
As much as it's awesome to have live-or-die battles with monsters, it's also awesome to try to hoard or build as much as you can, or exploring around and finding strange items, or even appreciating the randomness of the terrain generator.
HOWEVER. The way you put it in that post. Really makes me want to give it a try. You put every possible argument in favor of your modifications in there. Even fully aware that it's not my thing, that explanation makes so much sense that I can't help but think it's awesome. I should hire you for marketing. (well, it can do without the REAL MAN comments though, it's a game either way
)
