Fatshark's Lead and Gold: Gangs of the Wild West has been updated on Steam with a patch that includes a new map (Jacob's Bridge) and game mode (Demolition). The new game mode is a twist on the existing Powder Keg mode, but here teams are both attacking and defending at the same time trying to blow up each others objectives.
For our opinion on Lead and Gold: Gangs of the Wild West, check out the review. The game is also available on PSN, but there is no word when the new content will be available for Playstation 3 owners. And still no word on a Xbox Live Arcade release yet.
