Zombie Studios recently announced that Blacklight: Retribution is heading to Valve's Steam platform. The free-to-play shooter, a sequel to Blacklight: Tango Down, has been available for months via Zombie Studios' site.

The game will support Steam achievements and stats, and some in-game items will be created specifically for Steam users. No (re)release date has been announced, but we have an idea of what the price will be.
