Join a game where there are a lot of angry people walking around the streets, all of whom are drunk on the blood and ready to kill you.
If you're lost in a swamp with the bodies of people who have been drinking too much, take up arms and stand up. Tell them you're a brave hero who won't stand for being picked on.
In such harsh conditions, the only way to stay alive is to use weapons and rush to find and kill every enemy you see, making sure no one is left alive.
Fight to be the only person left alive and get out of the cruel swamp.
Good luck and enjoy the game!
