10 Embarrassing Accidental Video Game Leaks

10. Starcraft II: Heart Of The Swarm

Blizzard's StarCraft released in 1998 to go on to be labelled as the best real-time strategy game ever made. The game received a generously large expansion pack called StarCraft: Brood War later that same year.

When the hotly anticipated sequel, StarCraft II: Wings of Liberty released in 2010, it was pretty safe to assume that at the first sign of initial success, Blizzard would start planning an expansion pack. Sure enough, Blizzard's storyboard team were already working on Heart of the Swarm in early 2010 while Wings of Liberty's gameplay was being refined.

What nobody predicted, however, was that the expansion's ending would appear online before the game even had a release date.

The clip in question appeared to be an ending to the game's campaign, showing early stages of character animation, often merging with storyboards and missing lipsync. However the inclusion of the voice acting led people to believe that this was a credible leak.

Blizzard decided not to comment on the speculation, but sure enough, when Heart of the Swarm finally released over 2 years later, fans were surprised to see that the cheesy ending from the leak was in fact the real ending.

Talk about spoilers.
