Seafaring trade simulator Port Royale 4 has released its beta as a pre-purchase, with players who purchase the game now getting a discounted rate and instant access to the beta.

The latest in a series dating back to 2003's Port Royale, the trading sim takes players back to the golden age of seafaring in the Caribbean, acting as the governor of an island-based colony. In a new twist for the series, sea battles will now be turn-based, with up to 8 different ships involved in each battle.

See what else is new in the series with the closed beta, available now for players who purchase the game through the Kalypso store. The beta will allow players to play through the entire tutorial, plus the full Spanish campaign. It will also feature Free Mode again just for Spain, with four playable characters.
