Robot Onslaught: Multiplayer twin-stick 2D shooter using PubNubDistributed Systems with Node.js, O'Reilly 2020, has been published!
This weekend I put together Robot Onslaught. There's no server tech involved (save for simple serving of the files). All data is sent over PubNub.
Move around with WASD. Shoot in different directions using the Arrow Keys (I map them to a USB SNES controller for extra awesomeness).
I won the competition!
