10:10 swoop and tigerhawk are really good together. If you want to destroy the headquarters quickly. I recommend Optimus Prime. And the next strongest shooting bots. Head for the HQ and hit it with all you got fast and quick. But first make sure the beam lasers are destroyed. And the cannons.
I spend all my shanix on ore13 have been for years, I have normally around 40, +50 ore13 in my inventory so I use my combiner too, 5* god Neptune on zone15s "just like you said" I put down my bot I'm leveling down for a split second and go right at the hq with god Neptune and hold the fast forward the entire time, I can normally get all 75 fuel cells in 1 combiner time limit 😂 muscle memory, turn and burn i call it... I also put the gmedal xp core on the bot I working on, and with some coin I can normally can take 2 or 3 5* bots from lvl 60 to 70 in that way in a single weekend
