This is a small but very fun mod that decreases the choppers accuracy heavily, but also increases shooting speed to make it look much more cool.
1. Unzip "Cinematic Choppers.zip"
2. Copy the folder called "data" into you main directory. (the main directory is where teardown.exe is located)
3. Choose to overwrite any files if asked to
4. Just start the game and enjoy the Chopper. It's very unlikely they will kill you even when you stand completely still.
Not fully finished, as this mod doesn't change the chopper in the games final Frustum mission. It does, however work when entering Frustum with challenge mode and choosing "Hunted" mode.
