This papercraft is a Widow Mine, a terran-designed weapon, developed from the spider mine by Victor Kachinsky, based on the military science fiction real-time strategy video game StarCraft II, the paper model was created by poppaper. Widow Mine includes short-range jump jets and a fusion reactor.
Unstable Payload is an autocast ability that automatically activates when a widow mine is burrowed, and cannot be turned off unless the widow mine unburrows. This ability causes the widow mine to fire a missile at a target within 5 range, causing 125 damage and 40 splash damage. The widow mine then spends 40 seconds rearming.
Activate Mine: The mine takes 3 seconds to burrow, or 1 second after it has received the Drilling Claws upgrade at the tech lab attached to a factory. This upgrade costs 150 minerals, 150 gas and 110 seconds, and requires an armory. While unburrowed, a widow mine's priority is reduced. The ability is autocast and can be turned on or off in both activated and deactivated modes.
