Arctic Grave is an achievement in Joe's Adventures.


Push the chief witness into the ice lake in "Joe's Adventures."


In Witness - Frozen Memories you will chase the witness across a frozen lake. To get this achievement you need to kill him by pushing him into one of the openings in the ice that covers the lake.

You can do this in one of two ways:

  • Use the car you're driving to shove his into the water. This can be difficult because he's in a faster, heavier car, but it can be done.
  • You can get him to stop by forcing his car to the side near an opening in the ice or a chunk of ice sticking up. Pull him out of his car and shove him towards an opening in the ice. Keep pushing him until he falls in. If he fights back, which he may sometimes do, just make sure you don't finish him off and that you're punching him in the direction of an opening.

Once the witness goes into the water, you will get the achievement.


  • He has to be alive when he goes in, so killing him then pushing him in won't count.
  • If you miss this the first time you play the mission, you can replay it by going to the mission marker located by the dam.
