Brief SC2 information

StarCraft II features the return of the three species from the original game: Protoss, Terran, and Zerg^. The single-player aspect of StarCraft II has also been altered substantially from the original game. The Terran campaign shown at BlizzCon 2007 replaced the original StarCraft briefing room with an interactive version of the battlecruiser Hyperion, with Jim Raynor, now a bitter and hard-drinking mercenary captain, as the central character. In a departure from previous Blizzard games, the campaign is non-linear, with Raynor taking jobs for money and using that money to buy additional units and upgrades. Although each playthrough will vary, the end result will remain consistent keeping the storyline linear. Vice president Rob Pardo has stressed that each campaign will function very differently. The Terran campaign, Wings of Liberty, places players in a mercenary style campaign, as Terran rebel Jim Raynor performs missions for cash. The second release, the Zerg campaign Heart of the Swarm, will have RPG elements. The player will level up the Queen of Blades, Kerrigan, throughout the missions. In the last expansion, the Protoss campaign Legacy of the Void, the dark templar Zeratul will have to employ diplomacy between Protoss tribes to acquire units and technologies for each mission. Each campaign is expected to span 26-30 missions. Wings of Liberty has 29 playable campaign missions. Of this 29, only 26 are playable through a campaign playthrough since three missions are choice-related alternates. There is one secret mission named "Piercing the Shroud," which can be unlocked on the "Media Blitz" mission.

Lead Designer Dustin Browder has discussed with Shacknews some of the unique missions that are included in the Wings of Liberty campaign. In one level, lava floods the battlefield every five minutes, forcing the player to move their units to high ground or watch them get destroyed. In another mission, enemy units will only attack the player at night. The last mission Browder discussed was one where the player tries to influence the tide of an AI controlled battle with only a single unit, a Ghost. The single player missions will be highly customizable and are featured in the StarCraft II Community Zone. Between missions, players can choose units, buildings and upgrades that are not available in the multiplayer missions.

A major new addition to the map-making community will be the StarCraft II Marketplace, where high quality maps will be sold for a small fee as "premium maps" over Battle.net. The mode of payment has not yet been announced. Dustin Browder has mentioned that even maps like player-created DotA (Defense of the Ancients) in Warcraft III would not meet the quality requirements to be branded as a premium map.
