Gravitonia

Gravitonia is an Action / Strategy / Simulation game set in an immersive 3D world where the player is crafting their own units to fight the AI in the singleplayer campaign and other humans in multiplayer games. By wielding a gravity defying Graviton Manipulator weapon, the player can do scaling, merging, cloning, splitting, and replacing of various material type blocks. The crafting system is complemented with a module system and the ability to attach weapons and propulsion to creations. It's all done with free 3D rotation and positioning. All in all this gives the player artistic freedom and the power to fine tune their ultimate combat machines.

Custom units can be traded in the built in marketplace and skilled crafters will have their own hall of fame. If you like instant action, grab one of the pre-built units and go fighting. If you're more of a strategist, use your wits to craft capable units while you sit back and enjoy the show.

Built in updating system. Start playing for free, upgrade to full version during play. Once upgraded to full version, enjoy new updates and content forever.

The game should be finished, including the multiplayer part, around the time of the festival.
