an egg that's at 50% health hatches an Infested Terran with only 50% health. When it hatches, an Infested Terran emerges with health proportional to the percentage health of the egg, i.e. The Infestor throws an Infested Swarm Egg, which has 70 HP and takes three seconds to hatch. The spell, and with it the unit, were removed in Patch 4.11.0 in November 2019. The Infested Terran was a light, ground Zerg unit that was spawned by an Infestor using its Infested Terran spell.
