Back when I was looking to break into the game industry, I approached a few companies. Out of the four that I was looking at, I did tests for two of them. Now what you're about to see isn't my best work... in fact, when I was doing both of these tests, I was pushing myself as hard as I could. Staying up late and coming home to lunch to work on these was common. I did one fight scene for Sony Online Entertainment in Austin. That fell through, then I got in touch with a friend at Blizzard Entertainment to help me out and was approached to do another fight scene with an additional walk cycle. Here they are...nothing fancy.
