Sleeping Dogs

Complete all 28 open world events which consist of 17 Drug Busts and 11 Hidden Events - Hit and Run, Junk in a Trunk, and Shoplifter to unlock this.

Hidden Events only appear on your mini-map when you are in close proximity of the area where the events start, marked as a on your map and mini-map. The location of these events are fixed, and certain Events only appear during the day. If an event doesn't show up, try approaching the area on foot or heading to bed in a nearby apartment and then going back to the location.

• Hit and Run: Bus Depot - [North Point] Just opposite of north-easternmost parking lot. Chase down the thief and beat him up.
• Junk in the Trunk: Waterfront - [North Point] On the lower East side of North Point, there are two Parking Lots along the same stretch of road. In the middle is a path leading East to what seems to be a single Dock (NOT the actual Waterfront area). Head along this path and to the left there is a black car beside two abandoned and rusted cars. A woman is inside the trunk.
• Shoplifter - [North Point] From the North-Easternmost Parking Lot, drive South-West until you see a drunk standing in front of the shop. Drag him away. This event only appears during the day.
• Junk in the Trunk: Highway - [Central] On the highway East of Sui Shan Alley (where lots of construction barriers are), there is a side stop after the S-turn. A car is parked here, with a woman in the trunk. Release her
• Hit and Run: Valley - [Central] Just North of Siu Shan Valley, chase down the thief.
• Hit and Run: Parking - [Central] At Wang Fu Parking, go up a long flight of steps with an escalator beside it.
• Junk in the Trunk: Central - [Central] Walk directly North from the word "Victoria Park" and you should see a pedestrian bridge. Below the bridge hides a black car, and a thug in the trunk. Pull him out, and beat him up.
• Shoplifter - [Central] On the map, look for a building that is shaped like a "n". Slightly North from here, get rid of the drunk harassing the shop owner.
• Shoplifter - [Kennedy Town] From the South-East parking lot, head further down the road SE until you see this guy outside a minimart called Miss Quan. Grab him and throw him into the dumpster. This event only appears during the day.
• Shoplifter - [Kennedy Town] South-East along the road from the Massage Parlor, in front of another Miss Quan minimart. This event only appears during the day.
• Junk in the Trunk: Island - Aberdeen Island, just around the road corner, North-West of the words “Aberdeen”. Pull the guy out of the trunk of a car parked here.

Drug Busts, are marked as on your map and mini-map.

Drug Busts mainly consist of these steps:

1. Once you're at the location, defeat the thugs that reside there. Depending on their location, some of them will wield weapons or even firearms.
2. Look around for a security camera (it will glimmer), then follow its wiring to the security camera control box, and hack it.
3. Head back to one of your apartments, and hack inside your TV to gain access to HKPD's CCTV network. Select one of the four districts that has the label "triad activity" beside, then do the same for the hacked camera.
4. Identify the drug supplier, which is actually very simple; he is always the man in the suit that's standing by himself talking with a hand gestures to a group of gang members . If you want you can wait for the game to tell you which one's the supplier, as a shield icon will eventually appear over their heads.

Almost all Drug Busts are accessible on street level in Hong Kong, but there are few that can only be accessed through water, specifically the ones labeled "Sewer Treatment". To enter these areas, grab a nearby boat from a pier, and ride it to the location. Once you're near, you should see a sewer like tunnel entrance that you can head into.
