You can get this achievement in FIVE MINUTES
by using my custom map!
Go to SnapMap from the main Doom menu, and then go to Snapmap Community. Click 'Search'
Search by Keyword, and search for my map's name, "Barrel Kill Boost
", or search for my map's ID code, "ZR5T2BFN
Due to map-making limits, I can only put 60 enemies in a map (and only 12 enemies can be 'spawned' at one time, which is why I've put 5 rooms of 12 enemies). So all you need to do is play through the map once, get the 60 kills, and then play through it again for your achievement!
Make sure all 12 enemies have spawned in the middle of the barrels before shooting them! They will all spawn with red flashes of light.Please don't forget to upvote the map when you're done!Important:
This won't work if you download the map and play locally. When it asks if you want to download or play the map, you need to click 'play' instead of 'download'.
