Co-op 
Multiplayer Barrage is a 3D real-time strategy game where players will race against opponents to be the first to advance their planet and eliminate all enemies.
Business Model: Free-to-Play
Microtransactions: Yes, there are optional in-game purchases available.
Key Features:
Here's the Plan: Matches start you off with a few basic buildings, but you will have to gather additional resources and fund research to order new projects. Minerals are used in gun manufacturing and construction, whereas Energy can be collected to create new energy-based weaponry.
No Escape: Physics will always need to be considered when launching an attack on your foes. The gravitational pull of stars, black holes, other planets, and more can all cause your artillery to stray off the mark.
Go Long: There are five unique Research Trees available for investment. One of the paths allows you to upgrade your headquarters, while the other four allow you to enhance your Laser, Missile, Solar, and Graviton weapons.
Competitive Play: Play online with friends in game modes like Team Deathmatch and Survival, or in singleplayer game modes like Free-play.
