Web Spinners were a series of spider-based Bio-Organic Weapons developed by Umbrella USA. Though they had functional spinning glands, despite their name they rarely made webs with their silk. The Web Spinner was intended to be deployed to war zones and use its venom to injure combatants before eating them. The limited intelligence and less-than hoped strength increase made the series non-viable and it was largely discontinued.
Web Spinners were a series of spider-based Bio-Organic Weapons developed by Umbrella USA's Arklay Laboratory. These B.O.W.s were created through the primary infection of spider test subjects with an early strain of the t-Virus and were among the first bioweapons developed after the Arklay Laboratory moved on from viral weaponry to genetically-altered animals. While their increase in size was impressive, they were found unsuitable as front-line weapons on the battlefield. Their lack of intelligence made them uncontrollable and therefore a potential danger to their owners, and Umbrella was disappointed in their physical strength and had hoped for a stronger weapon. Their fast mobility and ability to climb walls was applauded, however, and they were instead re-evaluated as a secondary wave.[excerpt 1]
By 1998 the Web Spinners were declared unfit as weapons, and many were destroyed. Several Web Spinners were left behind for further research and later escaped. A larger mutant named "Black Tiger" settled a nest in the caves beneath the courtyard and gained a reputation for its strength that prevented the Arklay Laboratory's security team from tackling the nest. When the laboratory fell to a t-Virus outbreak, the nest were free to expand their territory.[excerpt 2][excerpt 3]
