Well, this one is self-explanatory. You can play on Casual, but beware of something important : if you're a completionist, you cannot get all the "collectables" like cash and resources and audio logs while going for the stealth achievement. To do both, save and reload when I will tell you in my third achievement walkthrough.

All collectables :

First mission :

Heavy weapons ammo upgrade in the corner room, hidden behind the flames before going up.
400 cr in the same room.
Audio log in the same room.
400 cr in the room after the 2 first guards.
400 Iridium in the room left of that, BEFORE jumping down.
Ammo in the corner, behind the next 2 guards.
Audio log in the room with the 2 guards.
400 cr in the same room.
Health pack under the elevator after you send it back up.
Data pad in the same place.
1000 cr in the room where you rescue Dr. Kenson.
Health pack and ammo down the next stairs.
Ammo on the floor and on some crates in a corner in the next room.

Second mission :

Heavy weapon ammo on the left in the landing room.
450 Palladium behind your shuttle.
1050 cr when you examine the console right of the door, same room.
525 Palladium just before the second door you have to open.
