Star Craft II: Wings of Liberty - Gameplay

Gameplay

StarCraft II features the return of the three species from the original game: Protoss, Terran, and Zerg. In the Terran campaign, the original StarCraft briefing room is replaced 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 play through will vary, the end result remains consistent, keeping the storyline linear. Vice President Rob Pardo stressed that each campaign will function very differently. The Terran campaign, Wings of Liberty, places players in a mercenary-style campaign, as Terran rebel group Raynor's Raiders raise funds by taking assignments from outside groups. The second release, Heart of the Swarm, will be Zerg-focused and have role-playing elements. Kerrigan will be the focus of the campaign, and the story will revolve around the possibility of her redemption. The Protoss-themed Legacy of the Void will be the final expansion, with the Dark Templar Zeratul attempting to raise funds and obtain supplies through diplomatic missions among his people.

Wings of Liberty has 29 playable campaign missions, but only 26 of them are playable in a single 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, by destroying a Science Facility in a corner of the map.

The Wings of Liberty campaign contains several missions with unique features, such as lava that floods the battlefield every five minutes, forcing the player to move their units to high ground before they're destroyed. In another mission, enemy units will only attack the player at night, forcing the player into a form of siege warfare. Finally, in one mission, the player must use a single unit, a Spectre, to influence the tide of an AI-controlled battle. The single player missions are 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. Lead Designer Dustin Browder has mentioned that even maps like player-created Defense of the Ancients in Warcraft III would not meet the quality requirements to be branded as a premium map.

Wings of Liberty features approximately the same number of units as the original StarCraft. Some units from the original game have returned, some featuring new upgrades and abilities. For example, the Protoss Zealot, a melee unit from the original game, now has the researchable ability to dash forward and quickly reach nearby enemies as a refinement of its speed upgrade from the original. Other units have been replaced or removed entirely. Other changes to unit design have been inspired by story events in StarCraft and its expansion, StarCraft: Brood War, replacing old units with new or renamed versions which sport different attributes and abilities. Units in StarCraft II have new abilities, compared to the original, that encourage more complex interaction with the game environment. Among these are the inclusion of units that can traverse varying levels of terrain, or have the ability to teleport short distances. Some Protoss units can be warped into pylon-powered areas using the Warp Gate, a slight modification of an existing building called the Gateway. StarCraft II's campaign also has exclusive units which are only playable in the campaign and not in the regular multiplayer mode, though they are available for custom maps. These mostly consist of units which have been scrapped from development such as the Terran Diamondback as well as various returning units from the original StarCraft such as the Terran Wraith and Vulture.
