Game modifiers

This can cause your account to be temporarily suspended or sometimes even banned because of modding. Even though you can go in to the files and edit them on the PC does not mean that it is okay to do. Only games that have downloadable mods like skyrim
and fallout 4 are acceptable.

I am with you on it cause I just have reviewed the web site and that is pretty much frustrating specially to those players that are not aware for that kind of lobby. I hope Activision's gonna take a look on it as well.

if the game developers allow mods and add in a menu for downloading and installing them then it's all good, but if they don't, attempting to mod the game could result in an Enforcement Action against the Xbox Live profile as this is explicitly against the
CoC and TOU.

you could try contacting the Developers of KSP asking if they have plans to add in User Created Content for the Xbox version.

Ive checked what performance I should be getting and its about right but the fps drops are weird cause its just random not when something should be loading

Still wouldn't do any harm to tell us what they are. I'm primarily a PC gamer and I know PC hardware.

Have you tried running MSI Afterburner to check your FPS and your CPU and GPU temperatures?

You will risk getting banned by the developers of the game in question as they tend to review such things!

even if its a single player game?
