Yes, pumpkin overlay is included as static hook in the basefile. Doesn't change much about the issue we cannot use the same hook, because it's an eclusive (if pumpkin then display overlay) thingy. With some creativity i could probably create an helmet inheriting the pumpkin class and messing and blahr and get something displaying the pumpkin overlay as well. Still not a nightvision, though.
Advanced HUD showing how much EU/Damage each armor/tool/weapon still have while wearing a Nano or Quantum Helmet. DO ITTTTTTTTTTTTTTTTTTTT!!!
