Is engine2 the same game? if yes then sure i can code an update to the loader that lets you do it..
rapid fire is not really a supported feature, it might be detected by the anticheat if you do it too fast etc, I haven't tested outside solo rooms because the game is dead.
First of all i wanna say i really do respect you for understanding and listening

And yes! it's the same game you just launch it from a different way i added a screenshot explaining it
The rapid fire actually does seem detected but it says i am getting banned by a moderator which just seems fake to me and is an anticheat ban or me getting banned by an admin but after the anticheat letting them know i am.
the game is dead i do agree.
but i know people and im kinda known or at least was known and i can help you figure this thing out i have experience with testing cheats out.
i used to upload videos of cheating on almost every game including valorant.
also lemme add that the way i launch engine2 is by going to the game files going to battleye folder pressing the belauncher.ini and editing it to something which i also included a screenshot to
