Well, with Super Chicken's inclusion in this, it was just a patch that made Super Chicken work alongside the others, akin to Cutman's NeoDoom patch that made the Vixens not so absurd. In the end, I'm still having people download your mod. With Truckosaurus, however, I'd be actually lifting some resources and throwing them into Doomvengers.
I've downgraded the Cuckoos so that they aren't COMPLETELY the end-all, be-all (they're mortal, they don't inflict pain, they don't loop their attack), but Cyberdemons will still get dragged down in a matter of seconds. That monitor is DANGEROUS, and continues for a couple minutes of utter carnage, but I don't want them entirely solving your future Gardener Cacodemon Problems.
