Satellite Reign

Satellite Reign was released last week on Steam for Linux, Mac, and Windows, it looks like everything I loved in the original Syndicate:

Satellite Reign is a real-time, class-based strategy game, set in an open-world cyberpunk city. You command a group of 4 agents through rain-soaked, neon-lit streets, where the law is the will of mega-corporations. Use your agents to sneak, shoot, steal, and sabotage your way up the corporate ladder, and take control of the most powerful monopoly of all time.

Each of your agents can be tailored toward your favoured play-style, while still maintaining their own unique specialisations. Shape your team into an offensive war machine, or an elite covert spec-ops outfit, and take the open-world city as your own.
