Above and Beyond Trophy
Above and Beyond
Collect 200 Team Boosts.
You'll find Boosts hidden in missions and dropped by bosses. Also, on the Stats page, you'll see that every character has special conditions to meet for unlocking some Boosts. There are also Boosts that unlock from the Challenge Rooms. You get different Boosts on legendary than on the other three modes. If you finish Legendary and still haven't got it, load up the Simulator and replay missions to hunt.
