I'm looking for 2000's to early 2010's FPS games with cool glitches like Exodus From The Earth. Thanks

Im using Yummy_Bacon5's practice dll and I can't get the granny tracker to work, or the map overlay that is listed at the end of the game. Im trying to optimize my runs and granny keeps getting me but I can't figure out why, so using this would help immensely. Thank you.
