Edit: I must have broke it. Banelings do not require the upgrade in version 1.0.
Currently, only the main and natural ramps have this effect (4 total ramps). I just wanted to do this map for fun, and maybe someone else can use it for something, just give credit where credit is due.
Press Ctrl+Q to receive resources and the centrifugal hooks upgrade.
Search for "Baneling Ramp Mod" in the Custom Game(not the arcade) showcase, or on the Galaxy Editor to download.
