Trion Worlds has announced that a new Freelancer will be added to Atlas Reactor on August 30th. Named Orion, The Empyrean, he is a support character that can deal AoE damage, heal and shield team mates. The official site has a full break-down of all Orion's skills as well as advanced tactics, tips and ways for opponents to counter him.
Orion is very unique support. He doesn’t naturally gain energy based on using his abilities, though they can be modded to do so. He’s got a passive similar to Rask where he gains energy every time he takes damage. For every 20 energy he holds, he gains 1 shard. These shards empower his other abilities but are only consumed when he uses his ult or dies (He’ll maintain 25% of his energy when he dies, which is 1 shard!).
You can read the full guide on the Atlas Reactor site.
