Onslaught! -- a history of violence (in images)
Onslaught! is a medieval fantasy arcade shoot 'em up. It was one of the very first commercial HTML5 games available to the world, launching on December 7, 2010 with the Chrome Webstore and has since launched on iPad and Android tablets.
HTML5 is taking off, the web is evolving, the Chrome Web Store is available in more countries than ever and one of these days we'll be announcing our next game, so I thought this would be as good a time as any to walk through Onslaught! and its near-successes. Here's a history of Onslaught!, in images:
1. First whiteboard
Geoff and I spend a ton of time talking, scribbling, debating and planning before we write even a single line of code. This is the first of many whiteboards we scratched out while developing Onslaught!.
2. Early environment test
We needed graphics but we didn't have any dedicated artist friends or extra money to spend. So I rolled up my sleeves, bought a Cintiq tablet and drew out some tests to see if I could bang out the graphics myself.
3. Whiteboard: game flow
4. Objects test
5. Couch development
This is a very typical setup for how we worked on Onslaught!. Some days we'd leave work and head to Geoff's for some game design, other days (like in this photo) we'd head to my place for gameplay tweaking on the big screen.
6. Whiteboard: enemy statistics
We spent ridiculous amounts of time tweaking the damage, health, behavior and interaction of the enemies in Onslaught!, hoping to provide retro gamers with an experience that would feel polished, and familiar yet new.
7. Dragon tests
I think at some point I found my stride with graphics, and to me the dragon turned out really well (unlike the minotaur). Dragons of all colors are interesting and nostalgic to us, but in the end you can't beat the classic "green dragon."
8. Google internal contest poster
I'm not sure that we ever publicly talked about this! As part of Google's internal promotion for the Chrome Webstore, they held a contest to see who could get the highest score in Onslaught!. The winner received an Amazon gift card. We later met with the best players to discuss issues with the game and how we could improve it for our players. Google intended to print these posters I made and put them around their campus. That never happened, but the experience was still invaluble.
9. Chrome Web Store launch
As early adopters of the platform, we were invited to Google's big media event where they announced the Chrome Web Store and talked about Chrome OS. It was really exciting, as screenshots of Onslaught! could be found around the extravagant event, including this one (Onslaught! can be seen below the word "Chrome").
10. New environments test
We were planning on bringing Onslaught! to iPad, and to help make the jump to a new platform successful, we wanted to add more content for gamers to enjoy. This was an early sketch of some ideas we had.
11. Sunken City
12. Demo party
As part of working with Game Closure's SDK, they graciously threw a release party for Onslaught!. Many players showed up from StartX for catered food and a brand new gaming challenge. Much useful feedback was had, as well as some shouts of victory that was a real pleasure for us to experience firsthand.
13. New and Noteworthy
14. Game Developer Magazine screenshot
One of the biggest thrills of my life was reading through Game Developer Magazine and seeing a screenshot of our game. Sure it's just a little mention, but you gotta start somewhere. I'm so proud I framed it and put it on my wall.

So what's next?
We're not totally sure just yet, but we'll be announcing something soon. Stay tuned, and thanks for reading.
