"Blunt Trauma: Perform Every Type of Predator Takedown (Achievement/Trophy Guide)"—This achievement/trophy requires a player to "perform every type of predator takedown." These can be performed anywhere in the game, and it will keep a running counter of what's been completed. Two simple places to do these early and get them out of the way: First when rescuing Poison Ivy (do a ceiling takedown from the rooftop), and second, during the Predator Fundamentals Training Programs, available after receiving the Batsuit v8.03 in the Falcone Shipping Yard. Just keep repeating that particular training program (3 takedowns at a time—use a checklist to keep track) until all have been performed. Note, that due to a glitch, this achievement/trophy might not unlock even after doing them all. If this happens to you, simply go through them again. To be sure, access the training program from story mode and not from menu select.
