The combat system in Traitors Empire combines SRPG gameplay with a card system. In each turn, your character carries out one move and one attack, and you can use as many cards as you want, so long as you have enough mana. Most cards give you an attack or defense bonus, but some allow you to move farther or use special attacks.
Traitors Empire has a strictly linear game development. The story begins with your protagonist escaping from prison, and from that moment on you'll battle your way through the main campaign. Along the way, you'll meet new characters that will join your group of rebels, level up your characters, and get new cards.
Overall, Traitors Empire is an excellent SRPG, with an entertaining and unique combat system. And, as if its classic story mode wasn't enough, Traitors Empire also has a PvP mode where you can compete against other players' teams online.
