Perhaps the most despised enemy in System Shock 2, the Annelid Arachnid is a pervasive, phobia-inducing spider that you'll come to loathe as you explore the Von Braun and the Rickenbacker. While the Infant versions aren't too tough individually, any more than one at a time will cause frustration as they leap and scurry around you. Unfortunately, it's very hard to minimise your contact with Annelid Arachnids, as they begin appearing on Hydroponics and will never let up afterwards, though the Infant versions will be mostly replaced with Adult and Invisible ones by the time you reach the Rickenbacker.

Annelid Arachnids come in three forms: Infant, Adult and Invisible. To see details on the other two kinds, please check their respective pages.

Attributes: Low Hit Points, low damage (Toxic), medium attack speed, fast movement speed

Weaknesses: Anti-personnel ammo, incendiary damage

Common Loot: N/A

Strategy: You'll be fighting a lot of Annelid Arachnids in System Shock 2, whether you like it or not. The Infant version is the weakest of the three, as it has a rather low amount of Hit Points and only does modest amounts of damage. However, a bit will usually poison you, doing significantly more damage over time. Unlike the Adult and Invisible variants, the Infant Arachnids simply don't have enough health to justify spending ammo on, so engage them in melee, as they'll be swarming you anyway. Suffice is to say, be vigilant around these enemies, and always have an Anti-Toxin Hypo ready.
