Blizzard expands Beta access for StarCraft 2: Heart of the Swarm
Beta access for Blizzard's StarCraft 2: Heart of the Swarm is expanding. The launch is set for March 12, 2013, so it makes sense that Blizzard is allowing more players to play the Beta. If you purchased the expansion digitally on Battle.net on or before December 18, you can now access the beta. If you pre-ordered after the 18th, you're added to the beta in waves, with new testers being added on a weekly basis.
Amazon is also offering promotional beta key codes for players who pre-order Heart of the Swarm at retail.
If you need to download the beta client, you can do so HERE. Note: only players who have beta access will be able to log in.
