This is not (yet?) in development, but is something I will keep an eye on.

The spiritual successor to Firefall

• Crowdfunded with small step milestones
• Unreal Engine 4
• A shooter first, with great movement, guns and abilities. Skill matters. Progression is horizontal, opening up more options, abilities, and gameplay
• Mining and gathering resources with the aid of huge, autonomous mechs. Resources matter, and finding and gathering them is fun
• Build and customize your own "omniframe" suit and weapons system. Customize them to your unique needs and the role you want to fulfill
• Sandbox world. Terraform the planet over time, create pockets of habitable areas and build refineries, defenses, and bases of operation

• Play a simulated world, with dynamic events. Go anywhere, do anything. Events will unfold around you as you play -- perhaps even war
