Is using rewasp a bannable offense in microsoft's online games such as Halo Infinite?

I take it you were referring to ReWASD? I am not a lawyer nor work for Microsoft/Xbox so this is my personal opinion and should be construed as such:

ReWASD seems to simply be remapping software so it is not gaining you any advantage over others so I don't see that it breaks the TOS. Actually configuring a controller to K+M settings will leave you at a disadvantage as using a controller is slower than K+M (generally)

On the other hand, you may be seen as breaking these:

"Don't Use unauthorized hardware or accessories"

"Don't Use specialized software to gain unfair advantage over other players" (This one is dubious due to whether ReWASD gains an advantage or not)

Hello dear Gamer, first it's a pleasure to be able to help you today.

Hey StormCrow1, how are you today? Hope you're well.

You mean reWASD?

Well, it's not clear, but every usage of any software that could facilitate you and get you ahead of other, yes, could cause ban.

See my other post. I know that healing is part of the game. Using infinite divine blessings is not. They are rare for a reason. And, regardless, glitching to get endless supplies of everything is against the XBL code of conduct and is a bannable offense.

No it is not a bannable offense, It is part of the game.

Absolutely not a bannable offense. It is in the game and you are playing it.
