On Day 55, you will have a chance to only fight drones for 3,000 to 4,000 Neo Yen each. It is possible to make well over 3 million Neo Yen through those fights.
The Scobee companies will have a special mech with better weapons available on days that are a multiple of six. For example, Day 6, 12, 18 through 60.
Go to the first stage on rumble (the city) and climb onto roofs for a good camping location, if you get high enough. Make sure you have a slingshot to shoot from the roof.
In the second stage underground, there is a large round room with a ramp that spirals down the wall. At the bottom end of this ramp is a nice location to camp out underneath. Even better, an ammo, health, and New Yen drop point is directly in front of you when you hide here.
Jump onto the "high rise" in front of you when you first enter the level. Jump up there and walk around to the left, then look around. You should see a passageway for you to pass through. Go into it halfway. This is a good location to let O.C. recharge or wait.
