If you are attacking a small group of troops, tell your zerglings to run *past* them, then as they begin running by and surrounding them, tell them to attack. tell them all to meet right outside of it, then once they have all gathered you can attack.
If they aren't killed instantly they'll start to spread out, but much slower than if you do it yourself.Īn easy way to get around this is to rally your troops before going into someone's base. Zerglings require more attention than most melee units as they are quite weak and oftentimes if a simple attack-move command is issued to a place that requires them to go around a natural or artificial obstruction, they will attack in a single-file line thus giving the enemy the opportunity to kill them 1 at a time. Zerglings are a key unit early game and it is vital to get the most out of them that you can. Against armored units your Zerglings may need the extra help. Cast Plague on the enemy at the start of the fight to reduce their health more quickly.
This is especially useful against Terran, where the only combat melee unit is the Firebat, not normally used en masse. Using Dark Swarm will render your units virtually invincible, since only melee units can hurt them. If things get too messy, the Defiler can cast Dark Swarm or Plague. The Zerglings engage in melee while the Hydralisks Engage from afar. The key to ambushing is to make the right combination of units: Hydralisks, Zerglings, and a Defiler is a choice combination. However, Terran Command Centers can lift off and reposition themselves to a more favorable position, so this does not work against Terran. If the Zerglings are Burrowed right, the opponent will not know a Zergling is there, but will build their expo in a more inconvient spot (buildings must be built a specific distance from the resources, and can not be built on top of burrowed units).
When Burrowed at a mineral depot, they can be an early warning sign if your opponent decides to expo. This makes them perfect for finding expansions. Zerglings are very easy to make, fast, small, and can burrow.
