This game we explored Koschei Complex to hit the safe guarded by the Rhino and Sniper. To do this we needed the Diamond Drill located behind the keypad locked door in Alpha Cluster. Pro tip: bring in a Car Battery and Jumper Cables, and even an R4 detector from a previous Koschei run if you don't succeed the first time. Go for the Drill first! THEN Rhino and Sniper!
