Brickade is the in The Ballad of Gay Tony game files but it never spawns anywhere. However you can spawn it with a trainer.
I've got a question to you all: Is anyone working on an ETK800 sedan? I've got started a little but in case someone has already some WIP I'll cancel it - would be stupid to have two equal mods.
I must accept that even when i play i couldn't find it so victory in this discussion is yours. Btw i probaly played that game for over 156 hours
Holidays coming in, I´ll have a lot of spare time soon! I had the same idea, that´ll be my next project.
