    that is so cool, I saw the other zombie simulation and was fascinated with it for a while, but i became quickly bored with the lack of the formation of any kind of society. I’ve been praying that somebody would create something like this and it seems that day has come. Can’t wait to see the finished product, good luck with your work!

    Thanks very much! I haven’t really been working on the simulator for the last week or so, but I’m hoping to get around to finishing the revisions and debugging sometime in the near future. Be sure to check back, because eventually I hope to make this available for download or Internet use, as I did with my heart simulation.

    hey, nice work. the thing that fascinated me the most in the original zombie game was the effect of the grouping of the zombies, kinda like a hive, I am legend style. do the survivors actually clump together or is that just by chance on that test? and the thing that pissed me off with the original one was that it was too small and it wasn’t an application that I could put on my computer. good luck!

  4. asymptote Says:

    Thanks for the comment!

    What I’ve observed is that, generally, the survivors clump for a while, but just before “extinction,” they tend to lose all organization and get driven madly in all directions, since, the way I programmed it, “panicked” people jiggle about randomly at high speed.

    is it possible to get it yet. this looks really fun and i want to play it.

  6. asymptote Says:

    You can find it right here:

    I think you have to have Java installed for the applet to run.

    when is it going to be out it looks so awsome!!!!!!!!

  8. legoless Says:

    Wow, awesome.

    When I tried it the first time with only 50 people, everyone was turned into a zombie except one normal human who remained standing in the same spot. No zombie came after it. Was that a bug?

  9. asymptote Says:

    It might have been. Being little more than a hobbyist, I didn’t do any kind of bug-hunting whatsoever, except when it came to really obvious bugs.

    HEy I dont want to be one of those pessimists, but I love the zombie infection games, and tthis one is great, but the only thing I dont like about it, is that when people hit a wall, they come out the opposite wall, which I find takes away from the game, say if the zombies are all on one side, and the humans are on the other, they are just to easy to get to, and I find that frusterating. I am voicing my opinion, but I am probably gonna get flamed

  11. Dak Rockson Says:

    I meant like the sides of the screen,not actual walls.

  12. asymptote Says:

    That’s a good point, but every time I’ve tried to incorporate walls into the simulator, they haven’t behaved properly. For some reason, the people kept getting stuck to them. That’s why I didn’t include them, and kept the boundaries wrap-around.

  13. Chuck Says:

    Wow, I tried it with 1000 people and I saw a fighter, leading I think about a dozen or more citizens, heading north west toward what I call ‘Helm’s Deep’

    Wickidy cool!

  14. Chuck Says:

    Also: people exiting from the south reappear in the north. about 200 or so lead by fighters retreated to ‘helms’ and everyone is running! I like it very much! thanks for making this.

  15. Tucker Says:

    You should add a white “hero character” but other than that it’s good

  16. Robbie Says:

    I think it’s great and all, but every time a pack of humans and a couple fighters meet up with even one zombie, they all die.. Come on, they can’t defend off ONE zombie?

  17. asymptote Says:

    Yeah…the simulator’s always had some balance issues. In the later versions, the zombies all get killed absurdly fast. I haven’t really hit a good balance yet.

  18. Joseph G. Mitzen Says:

    That sounds like a challenge for genetic algorithms… ๐Ÿ™‚

  19. asymptote Says:

    That, my friend, is an EXCELLENT idea! I think I could probably stick in some code to adjust a few key probabilities without much trouble and let the agent behavior evolve.

    You may just have made my day! ๐Ÿ™‚

  20. Timothy Says:

    This alot of fun. But the fighters seem a bit, eh.. how do I word this… Non fighters. They are more of a leader than a fighter. But they are still pretty cool. I love it when I saw 20 panicked, 8 fighters, and 4 norms in a tiny little room. It was hilarious. But other than that realy annoying downwards migration, very impressive social dynamics. Zombies should be hard to kill, and fighters hard to kill, while panicked and norms are average.


    with your downwards migration problem, did you know that like 70% of all animals have a tendancy to migrate south?
    And to the one person who sometimes doesn’t get infected? He/She is the one who is immune ๐Ÿ˜€ i love a good coincidence
