StarCraft II: Heart of the Swarm will be offered like an expansion, but is actually a full new game with a new story and a new set of characters. The trilogy has always been planned to be three different stories told from the point of view of a different race. This new chapter will continue where the previous Wings of Liberty left off and delve deeper into the life of the Zerg.

Blizzard has released the below trailer as well as a gameplay preview ahead of the E3 conference. However, the Heart of the Swarm most likely will not be available until sometime next year.

The confirmation come via Valve’s Doug Lombardi, who mentioned in an interview that downloadable content for Portal 2 was planned for release this summer.

‘We will be announcing some DLC for it, so folks can keep a look out for more content coming this summer,’ Lombardi told FastCompany ‘We’ll be putting more details out about that in a week or so.’

‘We’ll support that with more videos or more comics,’ Lombardi said.

Valve has already released one Portal 2 comic for free, Lab Rat, as well as some day one downloadable content – hats and accessories for use in the co-operative campaign. The in-game store hasn’t gone down well with gamers so far, however.
