Strategy
In most situations, crawler is the most efficient chaff unit, so almost any unit composition should include a number of squads of crawlers, purchased throughout the game. Their speed allows them to be easily chained to create chaff ‘waves’ which continuously distract the opponent. Once a critical mass of crawlers is achieved, techs like Subterranean Blitz or Loose formation are often purchased in the late game to make them more difficult to kill. While crawler is almost exclusively used as a chaff unit, it also features a few techs that provide alternative utility. Acidic Explosion helps kill aggressively-positioned giant units, while Impact Drill and Replicate are particularly useful to let crawlers win 1v1 against other crawlers.
