For the combat challenges, use the same basic strategies that you used for Batman. Robin does have two new maps that you will have to complete as well, Black Mask (predator) and Freight Train (combat). Freight Train Escape is the most unique of all of the challenge maps as it’s a side-scrolling map. To end it, you have to use a beat down on Black Mask and then destroy the blue control panel on the right side of the train.
While the predator challenge maps are the same (except for the new map), the requirements are different. The requirements can be seen by pushing at any time during the challenge. As with Batman’s predator challenges, patience is your best friend.
Robin’s gadgets are more similar to Batman’s than Catwoman’s. There are more to choose from and some function in similar ways to Batman’s (ie. shurikens are basically batarangs, explosive gel is the same, etc.). Below is Robin’s move list.
+ or hold + - Shield Bash
+ - Zip Kick
+ - Snap Flash
Note: The challenges that you have to do for the trophy are the same ones that you had to do as Batman, plus the two Robin maps. The following challenges DO NOT count for the trophy. Any medals that you get in them will not matter.
