As a response to Xenoma's response to my comment, no. None of your other games work for me either. I tried on Opera this time with the same result (as IE and Firefox didn't work before).
I'm sorry about that :( do my other games work for you?
This is an html5 game, make sure that your browser doesn't block javascript and is html5 capable!
Found a bug. If you fortify a subway entrance when there is a zombie horde in the other entrance, you can fortify the other entrance and the horde simply vanishes.
This game isn't difficult. You just have to think a bit and try to defend a small area at first, and keep that area yours while slowly taking the rest of the map. I did this and I never lost a single time the entire game.
