OpenZ, a remake of the real-time strategy game Z, has been released in version 1.4.
This free fan project based on The Bitmap Brothers’ 1996 classic is all about flags and territory deciding the battle, with time as the only resource.
New are the MAYHEM difficulty with fog of war, driver swapping in tanks, an improved General EvilZod and 10 to 20% better performance in large battles. The Mac and Linux builds are still considered experimental.
MAYHEM: A fourth difficulty above HARD. The enemy builds 10% faster, and the battlefield starts under a fog of war that only lifts where your units, buildings, and flags have been.
Driver swapping: Eject a tank’s driver and let another robot take the wheel. Sniping an enemy driver leaves his tank stopped.
General EvilZod: He aims before firing, recharges his dash faster, and charges nearby enemies when shot at from out of range.
Gameplay and controls: Rally points from the minimap, a REPEAT setting for build lists, scroll and camera options, and a new NUKE effect in the Unit editor.
Performance: Large battles run about 10 to 20% lighter.
