Heres a tip: if your looking for early damage go rank 3 Promethium mace (gives +24 attack damage) and a rank 1 Hawkmans harness (+65 health). After fight top node and head back to base; max promethium mace --> sell, max hawkmans harness--> sell, then you have plenty of credits to spend on whatever you want. eg. joe chills, rank 3 coda, crossbow, lobos, etc...
