WHERE TO GET H.R. ANNIVERSARY GAMETYPES?

Back in the day I used to exclusively play the Halo Reach game type “Anniversary Slayer”. It was a game type that came out when Halo CE got remastered. I LOVED this game type and I wanna play it using the custom game browser! I have tried looking for downloads for it (im on PC) to no avail. I have even tried using third-party game type editors, while this option did work i was not able to play this game type in the custom browser as it gets flagged by Easy Cheat and i get kicked from the game.Does anyone have this/these game types? (CTF, KoTH, Territories, Oddball), if so PLEASE add me so i can scoop them from you.
