4 new tracks including the EXTREME Tar Pits and 2 Daily Challenge Vaults have just been added to Bloons TD 5! From Beginner to Extreme, two of them available in Co-op mode, there's a bunch of new content to fill up time over the Christmas break.
The track consists of five short, circular paths that all surround tar pits. The paths that the bloons take change direction every other round in the web version, making this track very confusing at first. There is a big lake in the middle of the track for water towers. The player must have a Rank of 60 (50 on Mobile and BTD5 Steam) or higher to unlock and play it.
