Did this long ago was very poitnless to do maybe ok to try and get a final killcam with if you can show you putting it down in the kill cam some how other then that i thought it was poitnless. you can also do this with 2 sentry which then makes it look like you have 1 sentry but there is 2. and a couple others it works on aswell.
cause sentry gun requires 5 kills and ims requires 5 kills to so if you want both of them you need to change classes on the middle of the game so that glitch is a useless piece of shit
