my strategy is to equip the fist of fury and poison mace, at least. then just let ur food fill up while u use poison mace, wait a little bit, then use fist of fury. when food is full, launch all ur units. hope this helped!:D
to get the farthest down to the large diamonds: first, on your first run, just go straight down. you'll get more money. then upgrade your hull strength and fuel tanks. keep going straight down on all runs. when you can, upgrade your mech mole up to 3 or 4. then get nitrous. use the mech mole to get the coins and gems and sometimes drill through rocks. don't upgrade your steering AT ALL. it won't help you get more money. use your nitrous in the herder parts of the rock. also upgrade your drill strength. radar is also helpful so you can see where to send your mole for the most money. hope this helped! + so other players can see.
