Marvel Ultimate Alliance 2

The Trivia Rewards are the three little icons on the bottom of the screen for each question. To earn all available rewards from a question, it has to be answered correctly, quickly AND with a fusion in co-op. So, to get this achievement you will need to get a friend and quickly answer questions until the icons for every question in the game are lit up. Keep cycling through all the questions in a console until all three icons in the bottom right corner and lit up before moving on. A guide with all of the trivia answers can be found here. You will get this on your second playthrough since the final 35 questions are exclusive to an Act 2 base for whichever side you chose in the war.
