This Paradox Plaza beta signups page is where to register your interest in beta testing Hearts of Iron III, the World War II strategy sequel due for release later this year. Word is:

Hearts of Iron III is now approaching the critical Beta stage of development. The last few months have seen the team stabilizing the foundations of the AI, tightening up the rules and mechanics of the game, along with implementing new artwork and interface features.

Johan Andersson, Lead Developer on Hearts of Iron III, specifies what they are looking for in Beta Testers: “We require keen, enthusiastic gamers who are willing to give up a few hours a week to play a Beta version of the game and provide feedback to us on what they think. We want people to play it and tell us what they see. We want them to try and break the game in order for us to fix it and to test out our new advanced AI system to make the computer opponent better.”

Paradox Interactive is also looking for a small number of historical researchers to assist the development team in improving the databases.
