Let me break down the currency system since timing and strategy really matter here. When you're extracting items, you've got exactly 90 seconds before the taxman's platform starts crushing everyone, so efficiency is crucial. Making safe runs early on is better than risking everything for that extra loot.

The service station's inventory refreshes every 12 minutes real-time, and you'll want to focus on stamina upgrades first since they're typically 200-300 credits and give you crucial sprint duration bonuses especially during those tense extraction countdowns. Position yourself near the extraction point at 30 seconds remaining, because that's when the really nasty enemies start spawning.

For optimal credit farming, watch for the telltale red glow of gnomes - they're worth 75-100 credits each and have a distinct 3-second stagger animation when thrown. The extraction finder tool costs 500 credits but pays for itself in 2-3 runs by highlighting the fastest escape routes and spawning better loot clusters. Keep an eye on your inventory weight too since anything above 75% capacity slows your sprint speed by 40% which can be deadly during the final extraction phase.
