Too bad this game is no longer dev... because AI should really be added, a zombie that does not even see a human 10 meters in front of him ? Most of the time you lose because zombie just stay at the same place...
I still does not understand why the lemon is the the thing that give you the most... lvl 1500 766 tredecil for the same price 1100 oil 4 tredec... >_>
