If you're alright with it, I've sent you a friend request so I can send you those screenshots

I think that sound like a very cool idea. If you have Ace combat 7 maybe you would like to fly that mission for some clear shot of the cannon for me.

Awesome stuff!
This is probably a stretch to suggest, but would it be possible to create one of the Stonehenge guns from Ace Combat as a unique or park building? There's not really any assets that involve huge weapons like that. The only one available is Excalibur and it's severely outdated at this point
