In Case of a Zombie Apocalypse Break Glass

So in my quarantined state I've been pondering how I would prepare my apartment in the event that humanity is ravaged with any of the proposed zombie-type infections (this of course means I'm not affected and am currently surviving through it).

First off I'd need to get guns and supplies and barricade the main entrance; if people in adjacent buildings have managed to survive we'd create a supply line system for bartering supplies and whatnot.

Any travelling activity will have to be conducted through the rooftops of Buenos Aires (shotgun is a must).

I'm still working out the finer details but I'll be building my surivival kit slowly and surely.
