Upon launching the engine, you'll be greeted with a selection of default worlds to load. Each world is physics-enabled, allowing you to walk around, pick objects using your mouse, and even drive a car. These worlds are designed to offer a diverse and enjoyable experience

 The Sponza building, found in Dubrovnik, is showcased here with a true-to-life scale. |
A height map-generated forest featuring water bodies amidst tens of thousands of trees and plants, all set in a walkable terrain. |
| Car | Doom |
 A drivable car implemented with a highly realistic tire friction formula, simulation of gearbox, anti-roll bar, and more |
