This build is an aggressive zergling, roach and if appropriate baneling build which takes advantage of overly greedy terran players who take an early command center.

It may be appropriate to add a baneling nest at around 30 supply in order to bust a bunker/supply depot wall. Depending on how the attack goes you may want to continue to rally units to your opponent's base to push for a win. If the attack is held off by the terran player you can switch to a more conventional style of infestor/zergling. You will want to take a third relatively soon after the attack is held off as well as continuing to make units because it is very likely the terran player will counter attack with marines, medivacs and perhaps siege tanks.
