Big video here of Epic president Mike Capps and Gears 2 writer Joshua Ortega at Comic Con. This is definitely worth a watch. Key Capps quotes:
“Bayonets are kind of boring.”
“What was cool about the chainsaw? The blood splatter. The blood-curdling yell. The cool animation. That kind of stuff.”
“We obviously took a lot of great ideas from Kill.switch.”
Watch it after the link. There’s lots of stuff from Ortega on the plot for the second game after Capps’ intro.
