Arms Out of Harm's Way is a mission given to Huang Lee by Hsin Jaoming in Grand Theft Auto: Chinatown Wars.
Script
Hsin arrives in his Limo)
Hsin: The underhand dogs' weapons shipment is arriving right now. It makes my blood boil and my power of metaphor reach breaking point. I cannot allow a subordinate gang to stockpile heavy weapons they might use against us.
Huang: Sometimes, the hardest thing about being a parent is letting go.
Hsin: Shut your fucking mouth, you little cunt. Destroy their weapons and all those involved ... if you can.
Walkthrough
Go to the dock marked on your GPS. There is a spike-strip at the entrance, so you can't drive a car in. Grab the nearby Micro-SMG and kill the Midtown Gangsters in your path. When you reach the arms dealer, he escapes in a Speeder, so get on the nearby Wet Ski and gun him down.
Mission Replay description
