Swamps&Zombies (working title)

You are on a contaminated swamp. Each day new barrels with radioactive waste can be found. Collect them at night when zombies are less aggressive. When all barrels are found, dump them into the storage. Beware, during the day zombies will be attracted to ever growing pile of waste youve accumulated. More waste - more zombies. Look for supplie drops to help you denfend. Remember to place defences before storing barrels each night. Once they breach your defences all is lost.
