We’ve updated the StarCraft II Game Guide with two new pages covering features in the Heart of the Swarm single-player campaign. The new pages contain details on:
Kerrigan – Learn about Kerrigan's personal growth process, including the bonus objectives that’ll help her improve faster, the benefits of gaining levels, and some of the powers she’ll acquire throughout the course of the Heart of the Swarm campaign.
Evolution – Pore over a sample of the mutations and evolutions you'll have access to in the single-player campaign, including modifications to the Hydralisk and Roach. You’ll be able to change the Zerg Swarm to your specifications with short-term mutations, and permanently evolve each of your units into one of two different subtypes.
We’ll be adding more new material to these pages in the future. If there’s a gameplay feature you’d like to learn about, let us know in the comments.
