Let's talk positions and timings for those underground passages and hey, this kinda matters since there's actual strategy involved. First watch the radar when dropping into those tunnel entrances, since theres a specific pattern to hitting the collectibles down there. Those spaceship parts are tucked away in really specific spots and timing your approach matters especially near those branching paths where the echoes get confusing.

For the best results, you'll want to memorize those tunnel layouts near the drainage junction points, since thats where most folks mess up their escape routes. When the cops are on you getting the entry angle right is crucial - aim for those wider tunnel mouths and cut sharp left at the first junction. Maybe interesting to note that the monster rumors started because of those weird sound effects near the deeper sections, but its really just ambient noise triggering at specific spots.

If youre hunting rewards though focus on those last dose mission checkpoints instead, timing those completion markers will get you that ocelot virtue way faster than messing around underground. Speaking of timing when youre doing the ufo parts collection keep track of which tunnel sections youve cleared, since backtracking wastes a ton of time especially in those maze like northern sections where the water level changes.

Always worth checking those underwater cash spots too but remember to swap characters right when you hit the collection trigger, otherwise the timing gets messed up and you lose the exploit window.
