Video game developer Blizzard is using the currently running BlizzCon event to talk about its plans for the future and one of the big launches coming in 2015 is Starcraft 2: Legacy of the Void, the final installment for the strategy sequel, which received a trailer that's designed to suggest the complexity of the single-player campaign.

There's no actual in game footage included but the studio is using some impressive visuals in order to show the high stakes that will be featured in the coming narrative, which will see a Protoss faction led by Zeratul and Artanis working with the Queen of Blades and Terran leaders to oppose the force of the Xel'Naga.

Mike Morhaime, the chief executive officer and co-founder of Blizzard, states, "Legacy of the Void will deliver the quintessential StarCraft 2 experience. The new single-player campaign will wrap up the massive story, and we’re excited to share new game modes that will open up different ways to play the game and additional units that will expand the rich strategic depth of StarCraft 2 multiplayer."

It's unclear how many missions the game will include, but Blizzard says that Starcraft 2: Legacy of the Void will be offered as a standalone package in order to make it accessible to as many gamers as possible.

A focus on new modes for multiplayer matches

Starcraft 2: Legacy of the Void will introduce at least two new modes for gamers who enjoy the multiplayer side of the experience: Archon Mode and Allied Commanders.

The first one is designed to allow two gamers to control one base at the same time and Blizzard says the setup will allow them to execute more complex strategies as each one focuses on one aspect of the battle.

Allied Commanders is a cooperative experience focused on objectives that allows players to become the most important commanders from the series, each with its own set-up bonuses and special abilities.

Starcraft 2: Legacy of the Void will also include a range of new units, with the Lurker returning for the Zerg and the Protoss getting access to a new Disruptor.

There are also new abilities for already existing troops, with the Terran battlecruisers now able to use Tactical Jump to move to any place on the map, with more reveals coming during the BlizzCon event.

At the moment, Blizzard is not talking about the launch date or the price which will be attached to Starcraft 2: Legacy of the Void.
