just completed that quest. it was meh. first of all i didnt use nova tank as i couldnt transport it with andromeda, it didnt fit in unfortunately. so i just destroyed the turret with my ship.
then i went into the bunker. it was a bit more stressful than BH, but all went smooth. didnt get hit once, but boy oh boy is the NPC AI retarded. half of them just stood in the same place doing nothing, and the other half ran straight onto me
profit-wise its bad. doing bounty hunting i could earn 60k aUEC in half the time i earned 14k aUEC doing this.
but well, its something different to do. at least theres land and vegetation to look at instead of black emptiness of space.
someday ill get a starlifter just for this
but srsly, i hope they add some contracts to do on the ground with nova tank, because there isnt much use for it unfortunately
