Killer Instinct is a free to play game on the Xbox One that regularly has the only available character swapped out for a new one, meaning players can eventually try out all of the characters for free.
The latest character to be swapped out is Thunder (formerly Chief Thunder) for Orchid, a character returning from the original game. Orchid is known for her fire-cat abilities, and she is quite the formidable foe.
Orchid is a character hell-bent on taking down the remnants of the Ultratech company.
