These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
YMMV: Drone Tactics
Game Breaker: Centipedes. They have the best movement type in the game(treads), they have high Movement speeds. They have above average armor. They have enough default Barrier to negate most beam attacks. They have decent speed. But most importantly, they have INCREDIBLE gun attacks. They are supposed to be "anti-air gun units"...but like the Mantises, they can dish out severe punishments even to ground units, killing most in one hit, without the low hp and defense of a mantis. The only drone stronger then centipedes are the Scorpions, which are bosses that you are not allowed to use.
