Phaetonium is an engaging, action-packed 2D arcade/sandbox game with strategic elements. “Three-layered” world is one of the key features of this game. Each of these layers was created using its own style. The “Past” was made into an arcade-like fantasy. The “Present” resembles the worlds of sandbox games like Terraria or Minecraft. The “Future” has a futuristic theme with elements of strategy. Additionally, in order to diversify the gaming process, robots, combat vehicles, and transport were added to the game.
