The latest trailer released for StarCraft 2: Heart of the Swarm brings more to the table in features for both multiplayer and eSports. Bringing the ability to watch replays of previous matches as a group, and the new 'Take Command' feature, which allows you to jump into the replay you're watching and try out new tactics in a battle. More interestingly, you could use this feature to discover the weaknesses in a winning strategy, taking control of the opposing units, and trying to defeat them yourself. The final new multiplayer addition is the ability to recover a game after a player drops out from technical issues - network errors, power outages, etc - and play from where they left off.

In any case, with the massive eSports following surrounding StarCraft, it'll be interesting to see how these new features end up being used by the community. We'll find out on March 12th.
