>>5342348 The artillery spider is evolved into the heavy artillery spider. Its Mortar becomes bigger and expels its payload with more force. The acid it excretes becomes even more corrosive, changing to clear coloured instead of green. Its sniper eyestalks evolve a second eye each for better accuracy over long range. Its legs become heavier and sturdier to withstand the increased force, like the Heavy Guard Drone's. It loses its Bite attack and the mandibles alter their shape so they can plant themselves in the ground to brace the Spider for firing its enlarged gun. The increased offensive power of the new form comes with numerous drawbacks: It loses the ghili suit, its carapace softens and no longer confers a defensive bonus, it has a maximum lifespan similar to other overcharged drones, and the need to brace for firing makes it able to move OR attack in a single turn but not both, and the gun cannot be fired in close range.
The armoured booster battle hive is evolved into the corrosive artillery obelisk. It gives up much of it's hive support adaptations, including the the ability to spawn units in favour of a massive acid mortar.
Finally the super yakolev replaces it's torch weapons with web dispensers designed to clog enemy mechanisms, temporarily disabling them.
