Nacho's Terribad bug report and ramblings in StarCraft 2 Posted May 14, 2011 Intended? Wave 11 zerglings zoom forward randomly when attacked same with wave 18, 25, level 31? Actually I think what i'm finding is that the creeps will run to catch up with the creep in front of it. This happens a lot around corners, they seem to zoom around - not all creeps do this. Yeah this is intended, these creeps have an ability that increases their movement speed for a short amount of time. It looks like they're trying to catch up because they use this ability at set points rather than all at once.
