The Viper is the true face of the thin man from the invasion. Mobile and evasive, they serve as difficult to pin down skirmishers and are a common sight in the early-mid game. Early on they typically can be seen leading ADVENT pods, while later on they travel in full snake-packs, until they finally serve as auxiliaries for more dangerous aliens as the force level rises.
Long War 2 vipers have about the same combat strength, and are about as common as in vanilla.
Vipers are FAR more likely to use Poison Spit in Long War 2 if presented with grouped up targets or lacking a good shot.
A major change is that a Bound victim is now a valid target for the Viper's allies to shoot at. When facing several enemies, you may want to ensure the Vipers are disoriented, else a successful Tongue Pull early in the alien turn can result in the grabbed soldier being gunned down by easy shots from the Viper's allies before you have a chance to react.
- Tongue Pull, Bind, and Poison Spit are all single action skills, Vipers will always follow up a successful pull with a bind and can follow up a failed pull with another skill.
- Vipers will still poison spit at immune targets.
