I think it was a shooter but you had to use some stealth to sneak around as a spy

Agreed it was a very good guess based off the description but I don’t recognise the game at all so won’t be it. If I saw the game I’d know right away if it was right or not.

Thanks!

Checked it out and it wasn’t this. She had 2 outfits you could play in either and I seem to remember you did a lot of sneaking round men in suits

I can’t remember how old I was playing it but I imagine I was anywhere between the ages of 5-10 as I moved after that. So would have been 2003-2008
