Following its release on March 31, 1998, StarCraft warped millions of us through time and space to the 25th century, where we explored the unruly Koprulu Sector for the first time. We built armies and brought ruin to countless enemy bases as we helped the terrans, protoss, and zerg wage war against each other.

The release of StarCraft: Brood War just nine months later saw the Queen of Blades become one of the most iconic villains of all time, and the popularization of professional StarCraft competition in South Korea. Fast-forward through twelve long, anticipation-filled years to 2010, when StarCraft II: Wings of Liberty was finally unleashed upon the world. We guided Jim Raynor's actions as he fought valiantly against Arcturus Mengsk's Dominion forces, and cheered on as professional competition, now fondly referred to as StarCraft II eSports, exploded in popularity on a truly global stage. Now, with less than one month behind us since the release of StarCraft II: Heart of the Swarm, we're faced with not just Kerrigan and her ferocious brood, but the realization that time really does fly when you're having fun. In just a few short days, we'll be celebrating fifteen wonderful years of StarCraft.
We're pleased to invite you to take part in the festivities with a brand-new Feat of Strength achievement, as well as three portrait rewards which feature the original Terran, Protoss, and Zerg StarCraft box art.

Mission Objective:
Play one game of StarCraft II in any online mode before 11:59 p.m. PDT on April 17. (1 Remaining)
Beginning March 31, play one Arcade, Custom, Ranked, Training, Unranked, or Versus A.I. game to earn the StarCraft 15-Year Anniversary Feat of Strength achievement. As soon as you've received the achievement, all three portraits will be permanently unlocked in your StarCraft II character profile.
We have one final parting gift that we hope will embolden your forces to victory as you embark on this assignment. Please enjoy the stunning desktop wallpaper image below, which features full-body art for the Terran Marine, Zerg Hydralisk, and Protoss Zealot.

Commanders, the time to act is now. Rally your troops, log in to StarCraft II, and commence the annihilation of your opponents. We await word of your triumphs on the battlefield.
