Web Spinners are giant spiders mutated to great size by a primary t-Virus infection. Ironically, although called a "Web Spinner," they have evolved beyond the need for a web, preferring to chase and attack their prey more directly.
These spiders have kept their abilities to scale walls and ceilings and can often attack from unpredictable angles. They are however easily avoided, taking a moderate amount of damage before dying if fought. If killed, these spiders will disgorge a large number of young spiders which can bite and generally harass the player. This can be avoided by using fire-based weaponry which burns any babies the corpse may have been carrying.
Due to the Web Spinner's unpredictable nature, the B.O.W. research on it was suspended, and the subjects supposedly destroyed. A Web Spinner had a mutagenic reaction to the attempted killing. It became far more powerful and re-adopted the design of web building. This creature was known as the "Black Tiger".

Web Spinners are Infected cards introduced in Outbreak. Being of average Health and Damage (30 and 10 respectively) they aren't particularly noteworthy in Story Mode. Their effect in Outbreak Mode makes them dangerous however. When a Web Spinner is revealed, it raises the Exploring player's Infection Level by 1. This effectively negates the safety of Exploration in Outbreak Mode (which makes your Infection Level increase if you didn't Explore), and runs the risk of turning the player's character into an Infected Character, which is accomplished once their Infection Level maxes out at 10. It is one of the few dangerous Infected that can increase Infections, but is by far the weakest. The Web Spinner is worth 3 Decorations upon being defeated.
