The Web-guns were weapons created by the Yeti during the Great Intelligence's second attempt at invading Earth. The weapon fired a concentrated string of strong web material. When attacked with grenades, the Yeti could use the guns to cocoon them.

The Yeti also used the guns to spin a giant web that ensnared the Doctor's TARDIS. (DW: The Web of Fear)
