The back area of the map also contains a new crafting workbench where players can unlock new units and reconfigure their kits. Axes, saws, drills, hammers, and blacksmiths can be used to craft items. Blacksmiths craft weapons, engines, and armor. All but moudlesmiths can be used to craft one item at each station, and a single charge of a given item is available at each one. All resources are acquired at the various resource stations on the map, which are located at regular intervals. Each provider will supply a certain number of units per minute. For example, the Jade Forest has nine gems and supply 300 gems per minute, while the Lost Temple has 15. To acquire resources such as gems, minerals, and botanicals, units must be deployed to the resource stations.
In a press release, Chris Metzen, game director for StarCraft II, stated that the idea for expansion pack to Wings of Liberty flew out the studio "nearly 10 years ago", and that it was the largest production project within the company to date. The team behind the expansion was composed primarily of World of Warcraft and StarCraft II designers and artists. Lee-Sang Lim of Blizzard once again led the team, and he and Metzen considered the new project to be the studio's "biggest risk". Lim and Metzen wanted the new expansion to be a multiplayer experience. d2c66b5586
