If you thought you'd built a solid reputation as a Zerg ass-kicker, then you're going to have to go back to school and teach your opponents all over again, as phase 2 of the StarCraft II beta has come into effect, which means everything from the previous beta has been reset (presumably to properly integrate feedback changes and see the effects unhindered by a mash of old and new design or balance).

Beta participants will therefore need to recreate their characters and, if joining matchmaking games, complete a new series of placement matches.

Phase 2 kicks off through July 19, so be sure to warm up your fingers and take the game back through its paces.
