Frustrum Anti-Heli

I'd advise to make a copy of both of your original files and store somewhere if you want to get attacked by a helicopter again.

Endchopper instructions-

Navigate to your Teardown steam page and browse your local files, next navigate to data, then script and replace the endchopper file with the one here.

For the other file you want to navigate to data, then level, Frustrum, and then click script and replace the chase file with the one here.
