The Settlers IV is the 4th real-time strategy game in the Settler series, building upon its predecessor with some graphical improvements, new buildings and features.
You now can zoom in and out without steps and the game supports resolutions up to 1280×1024. There are 3 normal campaigns where the player controls the Romans, the Vikings and the Mayans, but there’s also a campaign wherein you fight against the dark side. Also there are enhanced multiplayer features and the game supports built-in voice chat, so Roger Wilco is not needed anymore.
The game basically is still the same, try to settle your little guys on a piece of land where another person also settled. Build your own economical system with food and weaponry production and then attack.

Notes:
Set resolution is 1024×768. Widescreen resolutions are not supported. CD-check has been compromised. Performance issues have been fixed. Multiplayer has not been tested. Cutscene Videos are included and fully functional – nothing was ripped.

Known Issues:
None as of yet.

OS version: 10.5.8
Processor type(s) & speed: Intel Core Solo 1.5 Ghz
