There may be an issue where you right click and get "movie not loaded" a fix for most is to right click, and select "check for updates". If this does not work, try switching browsers.
PRO TIP: Fill the melee slot as quickly as possible, they prevent zombies that get past from actually doing actual damage, if good enough melee'ers you can have 6-10 zombies come through, and won't take damage from any
