Step 1: Acquire Your Kosatka Submarine – Your Ticket to the Depths

Before customizing, you need the star of the show: the Kosatka. Head to Warstock Cache & Carry in your browser or in-game. Base price? A cool $2.2 million. But trust us, it's worth every penny for solo heist glory.

  • Pro Tip: Save up via casino work or VIP contracts—it's the fastest grind.
  • 1️⃣ Launch from your yacht or directly via interaction menu.
  • 2️⃣ Once purchased, it'll appear on the map as a blip. Fast-travel inside to start.

Ownership unlocks the planning screen for Cayo Perico, but customization is where the fun ramps up. No yacht required—pure independence! 😎

Step 2: Accessing the Submarine Customization Menu

Enter your Kosatka, approach the periscope or interaction menu (hold touchpad/scroll wheel), and select "Kosatka" > "Customize". Boom—you're in the upgrade bay!

Key areas:

  1. Exterior: Hull colors, lighting, and cosmetic flair.
  2. Interior Modules: The real money-makers for functionality.
  3. Weapons & Systems: Torpedoes, missiles, sonar—turn it into a war machine.

Customization costs add up quick, so prioritize smart. Total max-out? Around $9 million. But you'll recoup it in one good heist run. 💰
