Trial By Fire is a mission in Grand Theft Auto III given to protagonist Claude by El Burro from a payphone in the Hepburn Heights area of Portland Island, Liberty City. The mission becomes available after completing the mission I Scream, You Scream.
Mission
Claude answers a payphone in Hepburn Heights. El Burro tells Claude that the Triads had stolen a car of Burro's with some of his memorabilia. They then wrecked and burnt the car, so El Burro instructs Claude to get revenge by killing 25 Triads with a flame thrower. Claude moves to Chinatown, where El Burro had placed a flame thrower. Claude sets fire to twenty-five Triads and completes the mission.
Script
El Burro: Some insolent Triads stole my beautiful car last night, wrecked it and left it burning. Some of my most precious donkey memorabilia was in the trunk - real collectibles that are irreplacable my friend. I've hidden a throbbing weapon on the edge of Chinatown. Take it and teach these Triad vandals to feel El Burro's well-endowed wrath. Ariba!
Reward
The reward for completing the mission is $10,000 and the unlocking of the mission Big'n'Veiny. After completion of the mission, the Triads will become violent towards Claude if the player has not completed Toni Cipriani's missions.
