Metro Last Light

This achievement is pretty simple. When you get to the level 'sundown' you will hear Simon (the man that helped you out of Venice) say to find the church and to "stay out of the water if you want to live." It should give you a checkpoint straight away, and if you run forward a bit you will see a small pool of water. Dive into the water and Artyom will look around and jump out. You should see a disc spinning in the bottom left of your HUD. After you regain control, dive into the water again. This time a shrimp in the water should kill you, making you reload checkpoint. Simply repeat this process four more times and the achievement will pop!

Every time you dive into the water you should see the disc spinning, indicating it counts towards the achievement.

Note: After the second "dive" feel free to reload the checkpoint in the pause menu once the autosave symbol disappears, it saves a bit of time.

Firstly, load up the chapter 'SUNDOWN'. After Simon has stopped talking and gone, walk forward a few steps and you will immediately get a checkpoint. If you look directly in front of you there should be two ponds on your left and right. Use the left as it's closest. Jump in it and you will eventually come out. Jump in it again a second time and a shrimp will kill you, forcing you to reload your check point. After you see the spinning disk in the bottom left after the second time, immediately reload checkpoint as it counts towards the achievement and will save you a bit of time. Just keep doing that and your 'Diver' achievement will pop. Easiest 10g you'll get in this game.
