BloodRayne 2: Terminal Cut

The achivement pops up based on the number of baths you take

(It seems at least for me that in Level 20 "The Shroud Tower, climbing" (No.11 gate as I counted) does not disappear after you enter it, achivement can pop up if you repeat rhe action enough times. I have realised this especialy on this particular gate, i dont know about others.

Since this is most probably a bug, the developers might fix this sooner or later.

Also keep in mind that there are more gates in the game than the achivement requres ( 18 Total , 15 for achivement)
