I admire their ingenuity. The game doesn't look finished by any means but they're doing it the hard way, programming their own boards. It's not much of a game yet but I love that chaingun animation. The main gun feels very Terminator hunter-killer like. I always wondered if someone would try doing a whole new game sort of the way arcade games were made back in the day.
I too have often wondered about new arcade games made in the old way. It's the sort of project I would contract people to work on and dump a lot of money into if I had an unlimited amount of capital.
I love the perspective grid in this demo, as well as the ship, and the way the bullets spray around, (kind of like the War of the Worlds aliens). Really slick visuals and an outstanding start to this project.
