Leaper

Leapers are humanoid Corpus crewmen walkers with glowing blue eyes that try to tackle players from a distance; they will signal this action by stopping a small distance from a player and performing a battle cry. While not difficult to avoid, failing to do so will knock a player down for a few seconds, even if under the protection of Rhino's Iron Skin. Leapers will take significantly more damage while pouncing. After pouncing, or if players go outside their leaping range, they will run towards nearby players and swipe at them; these swipes are incapable of stunning players, but are extremely fast.
