The Chryssalid is a swift, four-legged alien with terrifying melee capabilities. Usually first encountered in small groups on Terror Site missions, Chryssalids deal heavy damage with melee and have a high chance to inflict poison.
When a Chryssalid kills civilians or soldiers, it will implant an embryo in them. This causes them to rise up as Zombies in the next turn, which will spawn Chryssalid Hatchlings after the next 3 turns. As shown in the Council Mission Site Recon, they can also use sufficiently large bioforms (such as a whale) as an incubator hive. Chryssalids are defined by the Ethereal hive mind as a huge disappointment for lack of controllability.
Killing other aliens with a Mind Controlled Chryssalid does not make them rise up as a Zombie in the next turn.
|Leap||Allows vertical leaps onto elevated surfaces during movement.|
|Poisonous Claws||Poison enemies wounded with melee attacks.|
|Implant||Victims are implanted with a Chryssalid egg if they are killed by a Chryssalid's attack (not from poison caused by Poisonous Claws).|
|Melee Only||Can only attack at close range; no ranged weapons or abilities.|
|Poison Immunity||Immune to all poison damage.|
|Hardened||Reduces the chance of suffering a critical hit by 60%.|
|Stun Immune||This unit cannot be stunned with the Arc Thrower; taking a live specimen is not possible.|
- Despite being obviously organic, Chryssalids cannot be stunned.
Chryssalids can cover great distances in a single turn, have enough durability to survive multiple hits from all but the heaviest guns, and ignore cover when making attacks. However, they will usually stay in one place for a period of time after crawling a long distance, even if a target is in front of them.
When facing groups of Chryssalids, you may wish to retreat to cleared territory before firing in order to create as much distance between you and the Chryssalid as possible, however; Assault soldiers with the appropriate critical boosting abilities and a Shotgun (or, more preferably, a Scatter Laser) can kill one with a single shot at point blank range. Naturally getting up close and personal with a Chryssalid is potentially fatal, so further augmenting this tactic with the Rapid Fire ability will greatly improve your odds of success.
As Chryssalids carry no equipment, you can use explosives to kill them without any penalty, as corpses will not be destroyed (and thus Chryssalid Corpses can be used to craft Chitin Plating, since equipping soldiers with that item greatly reduces the threat these foes pose).
Chryssalids are highly resistant to psionics; at 120 Will the chance to Mind Control is approximately 37%. As of update 3 of the game, at the Classic difficulty, the chance to Mind Control Chryssalid with soldier having 95 base will and wearing Psi Armor (115 Will total) is 60%. The soldier having 100 base Will and wearing both Psi Armor and Mind Shield (and having 150 Will total) has 85% chance to Mind Control Chryssalid.
In XCOM: Enemy Within, Chryssalids are very susceptible to a MEC's Flamethrower as revealed pods tend to advance together or bunch up around victims. In addition to wounding or killing a number of the aliens, the Flamethrower can also cause Chryssalids to panic and run away.
Although its poison is a useful ability, you should try to hold your Chryssalid in reserve and target only humans that will be killed in one attack. The ability to spawn Zombies is by far the most useful ability of the Chryssalid, and once spawned you should have them run away immediately until they mature into a new Chryssalid.
Although the Chryssalid can cover a massive distance in one turn by using both actions for moving, there is no point if you cannot attack after moving. You must keep it hidden at all costs until an enemy comes within range. One good tactic is to keep it inside a building near the wall, then have it leap up and attack unsuspecting soldiers on the roof.
Remember that Chyssalids do not receive cover, so it is useless to keep it directly on a corner. It must be at least 1 space back from the corner in order to not be spotted.
