I was surprised to find that you don't get a bonus for destroying a country.
Also, in the top left hand corner the mouse cursor tries to highlight invisible text preventing you from deploying anything. (most notable on the smaller maps)
Also, I went full melee (blunt) throughout the game, and came across only 1 Sledge hammer (damaged) so I ended up beating the game with only a shovel, even though I had searching over 100.
Strange how my computer can handle Deus Ex and the new Batman game just fine (fully 3d games) but while playing a flash game it lags out whenever I get overrun with zombies. I died 5 times trying to outrun zombies on the bridge when beating the game.
When zombies attack in hoards everything becomes super laggy and the games response time goes haywire. Right after this happened my companion went down and it wouldn't let me revive him. =\
