I made a esp for bo2 a few years ago and now i started playing plotonium so i tried the hack and it worked didn't even have to change any line of code. (same offsets)
Not every cheat will work, i reccomend you using a external cheat since internal cheat you need to inject because using internal you have to inject and they detected almost every method for injecting so yeah, my esp cheat was external,
If you have any questions add Desync#6723
