The siege against humanity

You decide to turn on channel 9, the news, you watch for a few minutes starting to daze off, but something the reporter said caught your attention, "attention everybody, tonight at 10 there will be a second attack, everybody is needed to either help with the volunteering or help fight, we meet at the lagoon at 7 O`clock, we need all the help we can get". The T.V. turns to static, you realize that you must do something or else you and everyone you know will die. You start getting ready, its only 4 but you need to go prepare. You can't decide whether to fight or help with the volunteering.
