The Mesets resembles a human-sized crow in appearance and has the ability to fly and chase after their prey. It's behaviour is similar to a common crow however, it possesses a greater intelligence than most mutations, choosing to attack its victims when they are distracted by other dangers. It's main venue of attack is to grab it's victim and after reaching a certain height, drop them which causes moderate damage. A Mesets will also try to rake opponents with its razor sharp talons. Mesets are a very rare mutation, only emerging from specific chrysalids during Jake and Sherry's search for the data files in the Edonian mountains, although Neo-Umbrella J'avo occasionally transform into them.
The Mesets relies on being airborne to sneak up on an unaware victim. It's only known attacks are slashing with its talons and grabbing it's prey, carrying them upwards and dropping them, causing medium damage. in higher difficulties they will grab the player causing a QTE event that will result in the player being thrown down the pits on Jake and sherry's campaign, unique counter for either character usually resulting in a one hit kill.
When it appears in Jake's campaign, the harsh snowstorm makes it very hard to see such situations. When encountering these for the first time, it is recommended to let the snowstorm settle for a clear visual. These creatures are usually airborne however, they will land sometimes attempting to sneak up on the player. When the snowstorm has settled, focus on the Mesets when they are airborne. Using Jake's Nine-Oh-Nine or Sherry's Triple Shot, unload on them until they go down. The same method applies on the ones that has landed.
The Mesets that spawn from Neo-Umbrella J'avo can be eliminated the same way, but extra caution is advised if there are other hostiles present. Mesets are also very vulnerable to flash grenades.
