Tetrapulse Kickstarter Campaign Underway and Trailer/Screens

Save infinite worlds with the only weapon you have left: your own life force
Chicago based independent game studio The Amiable has released the first video and screenshots from Tetrapulse, a two to four player, single screen co-op game where you and your friends join forces to battle a swarm of alien robo-bugs using the only weapon you have left: your own life-force. Every shot of your laser drains your health as you work together to protect the Heartstone, an ancient battery that powers you and your friends.
Its Kickstarter campaign page is located here.
