While exploring the Resort map of Act I the Hero may catch a broadcast from Richard Case. The message reads:
Hello, if anyone can hear me, I'm trapped in a lifeguard booth by the beach. I'm surrounded by the infected and they are clawing to get in. I need help! If someone can hear me! Please hurry!
Richard can be found in a lifeguard booth in the Diamond Beach area, close to the coast (it is near the "bar island" at the lower passage to Diamond Bungalows). There are several zombies trying to get inside the booth.
As a reward for rescuing him, he gives the Hero the keys to his house, triggering the side quest "House Full of Surprises." He tells the Hero to take whatever they want from his house, and states his intention to get off the island. If the Hero returns to the lifeguard booth later on, Richard will have already left.
