The base level weapon. Extends 3 branches from the landing site, and finishes with 12 sub-branches. Being hit by any of these branches causes 25 base damage.
Similar to spider, but does less damage, and it finishes with 18 sub-branches, allowing potentially more hits. Each branch and sub-branch travels farther than spider.
Daddy Longlegs, like the name suggests, has its "spider legs" reach out noticeably farther than any other variant. It splits only twice, which is the least out of all variants, but finishes with 25 sub-branches.
Black Widow goes back to the normal reach of spiders. Although damage is reduced to 14, it splits four times, which is the most out of all variants. It finishes with 36 sub-branches, so it tends to completely block out the area where the shot is landed.
Although you may rarely get the chance, if an enemy is inside a circle bumper, shooting any variant of this weapon inside of the bumper can cause major damage. This is especially true if the bumper is small and the enemy tank is in the center of the circle.
