The website is live, with a short round you can play right on the page: drag to move Rook, let go to shoot, pick level-up cards to recruit Brick and Patch, and bring down a Stomper. It works on phones and computers.
It's a taste made for the web: four rooms and a boss. The game itself has whole Operations of 25 rooms each, five specialists, gear and many more bosses.
Squad Shooter: Rook & Rex is coming soon to Google Play and the App Store. Names and details come from the game as it is today and may change before release.
