Yes. The holy missile silos, the ones where you nuke everything and have flaming eyes spawn (Damn you all flaming eyes!) for no reason!
What I was thinking, is the payload these things drop.
Nuclear/ICBM/Tactical Nuke: These would be super, super rare but amazing. If you consider blowing up about 2/3s of the map up, leaving a radioactive crater !!FUN!! like I do.
Special Affects: If hits river, River becomes radioactive. City Hoard Spawning stops, Random Jabberwocks in area! (or mutants…)
Acid: These would destroy houses, loot, zombies. But if launched just right, you can get rid of that pesky fungal area without destorying everything, leaving it habitable.
Special Affects: Can pollute river, kills most of wildlife.
(I would add more, but my laptop is almost de-)
(Feel free to add more, I’ll be back tommorow.)
