Got the skills to write a guide? Be our guest! Alpha 2 introduced players to Terrain sculpting. Build caves, mountains, tunnels, virtually anything with the new terrain tools. Alpha 3 brought us terrain painting, allowing players to simulate snow, rock, desert, lush greens. It also brought us water. Use sculpting to dig lakes and streams and use the water tool to fill them in. Calm, rough, standing and dirty water are all options that are available.
