I didn’t rush to get all of the Crimson achievements, as I thought that the Crimson playlist would remain to play forever, however I am aware that the playlist is now gone and that you can get the map Shatter in BTIS and Dominion playlists to get the bigfoot achievement. I can not find a lobby at all that has Shatter available to vote in it. Could anyone give us any help as to how I can earn this achievement, any help would be appreciated. Thanks

You are going to have to get a group of at least 7 other players together, and hope that the matchmaking system finds enough players on the other team to fill out the game.
If one person doesn’t have the DLC, then the map does not appear on the selections.
big team, it pops up all the time.
biggest tip for you is this
dont leave the lobby after every game. Stay put.
i got it in big team.
although it didn’t work too well for me, camping by a teleporter worked for others. you could get 2-3 kills a game.
Thanks for all your reply’s. I was backing out of all the lobbies but I’ve decided to stay put now. Thanks again.
