Splash Damage's upcoming free-to-play shooter Dirty Bomb has kicked off it's closed alpha process, with a limited number of "Founder's Club" hopeful having been invited to help playtest the game. The developer has also released a new trailer, offering some more insight into the development process, and some more gameplay footage.

Titled "Shaped by Gamers" the video discusses "Echo" an analytics system created to assist with balancing level design, created by a team led by Dave Johnston --who the video is quick to remind us, was the creator of the quintessential Counter-strike map de_dust.
