Like Galaxy's End
and The Black Corsair
, No Gravity
is a PSP game that's looking for a publisher. Unlike the other two efforts, however, the developers of No Gravity
are asking PSP homebrew users to download and try their game. This 3D space shooter comes from a team called Realtech VR. The final version of the game has a planned 55 missions, "with diverse objectives ranging from destroying enemy ships or base, escorting allied ships, clearing the mine field, etc."
