Scientists and Combat Strategy
Small Oil Rig is guarded by armed scientists that deal consistent damage and patrol actively.
Tips:
- Clear from the bottom up
- Use ranged weapons to reduce damage
- Prioritize headshots to conserve ammunition
- Avoid fighting multiple scientists at once
- Bring sufficient medical supplies
For solo or duo players, killing visible scientists from a boat before boarding can reduce early pressure.
Keycard Puzzles
Small Oil Rig contains multiple puzzles that require keycards:
- Green Keycard (Level 3): Mid-tier loot rooms
- Blue Keycard (Level 4): High-tier loot access
- Red Keycard (Level 4): Best loot containers
Don't forget your keycards!
Locked Crate and Heavy Scientist Event
Activating the locked crate on the top platform starts a timed event:
- A 15-minute hack timer begins
- Alarm sirens activate
- A Chinook helicopter arrives
- Heavy Scientists deploy onto the rig (helipad)

Heavy Scientists have significantly more health and firepower than standard scientists.
