Tom Clancy's Splinter Cell HD

The best level for this is the Kalinatek level but there are other spots in other levels where you can disarm them. To disarm a wallmine simply crawl up to it slowly to the side of it until a disarm option appears. When the light on the mine flashes green press to disarm. If you press it on red get out of there as it’ll explode. If you are eager to unlock this trophy, after you have some wallmines in your inventory simply one, two or three of them on a wall and just deactivate them when they activate and repeat. I tested this to see if it worked and it does.
