Ziggurat

This game has no checkpoint system and no quicksaves like most games lately. If you die, you have to start the game over from level 1. If you do not die enough during normal playthroughs to get the other achievements, or if you simply want to grind this out, just set your difficulty to normal (hard if you have it unlocked) and start a new game. Walk into the next room and just let the enemies kill you. 9 times out of 10 the room next to the starting room will contain enemies and if it does not just walk into the following room to die on purpose. After you have died, press to start again from the begining and repeat until necessary, the Xbox one's achievement app (and this site) track how many you have to go until this achievement unlocks.
