SLEEPING DOGS DE ACHIEVEMENT SAVES

These are a collection of saves that you can use to be able to get certain achievements on Steam.

HOW TO USE:

Just download the saves and overwrite the saves you have that are located at:
Steam\steamapps\common\SleepingDogsDefinitiveEdition\Data

I would recommend you guys use 1 (ONE) save at a time.

SAVE 1
Bounty Hunter - Do the Collector Mission

SAVE 2
Whatever's Handy - Do the mission with Jackie (call him on the phone). Playthrough it long enough and you'll get a handsaw/ripsaw in the docks. Use it on the enemies you encounter and the achievement should pop.

Save 3
Super Cop - Just do the mission "Important Visitor" and you should get it at the end of the mission.

Save 4
Karaoke Superstar - Go to the nearest karaoke and finish "Take on Me" with at least 90% Rating.

Save 5
Foodie - The last meal missing is a "Noodle Bowl". I managed to find one at Tsim Shan Alley, near the Police Station at Central.

Save 6
Martial Law - Go fight the final club in Aberdeen

Save 7
West End Scavenger - The final box is in Aberdeen. It's on the collectible map. It's by the highway.

Save 8
Spiritual Healing - The last shrine is in Night Market, North Point.

Save 9
Mr. Nice Guy - Last favor is "Broken Parts"

Save 10
Ultimate Fighter - Just redo the mission Bride to Be, and make sure to fight all the monks in the temple.

Save 11
Case Closed - Just do the final blue folder mission.
