OUTRIDER - Her special ability is called Vision Pulse. This gives him a massive speed boost for a short time. RUIN - His special ability is called Overdrive. Before a Specialist can be chosen, an unlock token must be used to unlock its Special Ability.Here is a list of all the Specialists and their abilities: The others must be unlocked by leveling up. Four Specialists are available at Level 1 in Multiplayer. That said, you must use the SECONDARY ability of whatever specialist you are the most comfortable with. I've even met someone that had unlocked 10 medals using all the specialists and didn't unlock for them until they had 75 medals overall. I personally unlocked this achievement after 23 'Bully' medals playing the game legit by using only Battery's Kinetic Armor ability and no other Specialist, noticing that host migrations and server disconnects still counted all my medals but not for the medals obtained during any match where connection issues occurred. Edit: Thanks to Luuc and AypL who can confirm that this achievement is obtainable during one COMPLETE match, especially if boosted with another person/dummy account.
