Video 2 Video 3 Explorium is a multiplayer 2D sandbox game with infinite terrain. With this game we am aim to create a sandbox game that doesn't fall to the woes of pointless tiering up and boring linear progression. The game will instead contain a much less linear progression, and a much bigger focus on pure exploration.
Right now the game is in pre-alpha. When the game reaches the alpha stage it will be free-to-play. Later on we plan to sell Explorium.
