I can vouch that everything works. The "Invisible Wall" hack will take away all the "wood" panels in the game. That means all the floors too. You can't go upstairs to grab items because you will just fall thru the "floor". Walking on areas with any elevation from the outside ground, you will have glitching problems, which is hard to play with. Shooting people thru the wall works, but will get banned once enough people report you.
The chams works great, but you can't see people behind the wall(ESP). I'd rather pay a little more and have the wall hack, but i guess $70/lifetime is still ok.
