this is an idée that i think is relly cool. basicly it´s a granade you trhow and robots around it will get hacked and die.
I think something along the lines of an energy-expensive grenade launcher would help quite a bit dealing with hordes. As it stands, there aren't a whole lot of options available for reliably giving you breathing room (stupid Mk.II Jetpack Bots), so having a weapon that staggers or removes special capabilities (jetpacks, secondary swords, etc.) from groups of enemies.
