Heavily influenced by Terraria (a famous Minecraft clone in 2D), Orion is a sandbox type of game where you can unleash your imagination and shape the world in your image. Peaceful during the day, the universe turns hostile during nighttime with the spawning of hungry zombies. The game features many missions such as survive the first night, build a shelter and place a bed, craft weapons and armor, raise level, plant a vegetable garden, smelting ore or unearth relics hidden in dark dungeons.
