Only experienced this twice so far, both times using a cluster bomb. Basically I set the timer to 5 seconds, launched it off, the enemy hedgehog was by a hill, the cluster bounced behind him & got stuck betwwen him & the terrain, kept making the sound like it was bouning off the terrain until the time lapsed & it exploded releasing the clusters.
