Xenus 2: White Gold

Summary pulled directly from Steam - Some text may only be applicable to Steam platform

Caribbean islands; islands full of secrets, mystery and the spirit of romance. These islands are both beautiful and lethally dangerous. Centuries ago the waters of this region were teeming with pirates and adventurers... and frankly, not much has changed since then.
Many books have been written about the Caribbean basin and many films have depicted it.
Now you have a unique chance to visit these places yourself and personally witness the everyday life of drug-dealers, bandits and the Mafioso. You'll be able to take part in various mysterious events and get involved in fights between various hostile forces, or just admire the luscious tropical environment while drinking the traditional pirate's liquor - rum. The Caribs are waiting for you!

The main hero arrives on the islands in order to investigate a series of mysterious events, but he instantly ends up in troubles that only you can help him with.
