Is there anything more after I finish the story?

There is little information about Vector 2 at this point, outside of the wiki entries for the "Legacy" of the original game.

The game received a 2016 sequel titled as Vector 2 that continues the storyline of the original game. The protagonist from the first installment was eventually captured by security forces at the last stage of the location Technology Park. But instead of killing him, the security forces decided to test and use his skills and stamina with the featured new equipment in a secret research laboratory/facility. In the original sequel, the final story is not yet revealed stating that the game is still ongoing because Nekki is working on games such as the series of Shadow Fight.

Additional levels have been developed at this point, as the player enters a maintenance area of the Facility, however it appears that this is where the development for the game has stopped. Very few updates have been released, and Shadow Flight is constantly being advertised with in the Vector 2 game.
