Some energy drones won't shoot even if the player's energy lv still at a healthy lv. A bug or smth i don't know abt?

Every energy drone needs energy to work.

so if u have very less energy there is no power to work it


if u have less energy REGENERATE mech do not use an energy Drone

or may be when u teliport and use a sword ur energy will drain itself so may be that's the reason its not a bug

The problem could be this: your mech do not have enough energy so your drone can't shoot. After you realised that your drone didn't shoot you check the energy level but it says it has enough energy. Its because your energy have been regenerated after your turn so it shows you more energy (depend on your energy regeneration). So you didn't have enough energy, you just checked after your turn when you already regenerated.

Your energy level- your mech's energy regeneration= your energy in the actual turn. If this number is lower than your drones energy need you can't shoot.

All of the above statements are correct, I would also like to say that if you miss a turn because of overheating, your drone won't fire!

Also make sure it doesn't take any additional ammo you may lack.
