This week's addition to the NVIDIA Grid is REVOLVER360 RE:ACTOR. Each week the Grid receives a new PC game available to stream for free to NVIDIA Shield Portable and Shield Tablet owners.
Revolving the world of the game is apart of the main premise of the game. While piloting your ship you are shooting at various enemies with lasers. Along side the main game is a series of mini-missions in Challenge Mode.The game has a unique visual style, within a world of mainly blue, somewhat similar to the original Tron movie.
The NVIDIA Grid provides many PC games to stream for free, and will continue with the incredibly low price of nothing until the end of June. Plans for the Grid after then have not yet been revealed, though I think it is safe to assume we will learn about it at E3, also this June.
