Dingo approaches a heavily guarded truck in a secluded parking lot in an industrial area of San Clemente to pick up his orders -- to "stalk" and "kill" his target.
But all is not what it seems.
Dingo, a regular at San Onofre surfing beach , is playing "StreetWars," a version of a popular high school and college game "Assassins" that kicked off in San Clemente on Monday with around 240 players.
Dingo is given a photo, name, home and work addresses and phone number of a target whom he must pursue and "kill" with a water pistol, water balloon or other water-based soaking, while eluding the player who is coming after him.
"I thought it would be fun, a way to meet new people, even if I die in the first week," said Dingo.
Contestants pay $40 to enter. The winner gets $500, a bottle of Jack Daniels and a water gun mounted on a trophy.
Game co-founder Anonymous, dressed in a vintage suit and aviator glasses, also known as the Supreme Commander, said the game was born largely out of boredom.
"As a kid we used to get around and play in parks, and use the city as a playground," said Anonymous, a 75-year-old lawyer. "I kind of wanted to make it a place to play in again, particularly as an adult."
Others agree. After making its debut in San Clemente, "StreetWars" has been played in Los Angeles, San Francisco, Vancouver, London and Vienna, Austria, with games also planned for Rome, Paris, Amsterdam and Reykjavik, Iceland.
Anonymous plans to develop the game into a reality TV show.
