Starcraft: Remastered is finally seeing the light of day on PC on August 14th. This updated version will have "4K Ultra High Definition graphics, enhanced audio, new matchmaking and leaderboard systems". So pretty much what you would expect from a modern RTS game.
Starcraft: Remastered is compatible with the original Starcraft, so people who buy the upgrade can play with people who already have Starcraft and Starcraft: Brood War.
All who pre-purchase the game before August 14th will get "three unique building skins for use in Starcraft: Remastered—the Char Hive, the Korhal Command Center, and the Aiur Nexus".
When buying Starcraft: Remastered you will also get "digital bonuses in Starcraft II, including the Alexei Stukov co-op commander and three unique portraits that celebrate Starcraft: Remastered".
Blizzard's Mike Morhaime added: "nearly 20 years ago, Starcraft welcomed millions of gamers to an epic sci-fi universe—and also helped form the foundation for esports as we know it today. Passionate gamers around the world are still playing Brood War, both with friends and competitively, so we're modernizing the technology behind Starcraft so that they can continue to enjoy the game for many years to come."
Starcraft: Remastered will set you back $15 (USD), which usually translates to €15 and just below that in British pounds.
