Description:
In the Untahris Common Playground, you can play several classic fun, simple arcade games, including games similar to Tetris, Snake, Tron, Arkanoid, Pong, Thrust, Bomberman, Rampart, Liero. You can play them both in single player and multiplayer mode (on one computer, local network, or maybe Internet). Now, Untahris has an original experimental feature, which makes it more than just a bundle of these games! In multiplayer mode each player can play a different game -- however, they play all on the same board. This may lead to funny interactions, battles or alliances between them. The games in Untahris have been modified to make them better interact with each other. Thus, each player is allowed to shoot and collect bonuses, even if it was not a part of the original game this player was based on.
