Some upgrade ideafor Helium Tank I had when I was using the Hydrogen Tank upgrade(I like the MOAB reference lol).
ooh
zeppelins are in fact planned to be part of a hydrogen tank upgrade
however i have a very different ability in mind..
i do very much like the propane tank ability tho
If you wanna add the Propane Tank,can you make the Hot Air Balloons explode on impact? Because it filled with highly flammable gas called Propane.
