Concussive Shells is a Marauder upgrade which is researched at a Tech Lab attached to a Barracks. Any enemy units hit by the Marauder's attack have their movement speed reduced by 50% for 1.07 second. Their attack speeds remain unchanged.
The effect does not stack but will be refreshed with every hit. Note that an unstimmed Marauder also attacks every 1.07 second.
Massive units and Structures (e.g. Spine Crawlers) are not affected by this ability.

Use

Concussive shells plays a large part in any bio army. It prevents an opposing army from retreating without additional losses, as well as giving the Marauder that ability to kite incoming units with ease.

In Combination with Other Spells

• Stimpack - in combination the Stimpack ability, the Marauder can easily hunt down all ground units it encounters, due to speed bonus afforded by this ability.

Notes

Concussive Shells is the cheapest upgrade in the game in terms of resource and time cost.

Due to the change of timing in Legacy of the Void, the timings are different in the last expansion than in Wings of Liberty and Heart of the Swarm. In the previous expansions, the Concussive Shells ability took 60 seconds to research, and lasted 1.5 second.
