We haven't had a chance to watch the video yet, but here are our thoughts coming in.

Lauren and I are thinking that this is a last chance inventory round, more than an elimination round.

Sporting good store: Turns out that the lower floors usually have cloths, shoes, sports equipment, guns, jackets - but most good items are probably already looted. The second floor often has camping equipment like tents, firestarters and food-rations. It is true that people are more likely to be hiding on the second floor than on the first.

Walking on the street has it's own dangers, we already know that there is a sniper on the roof from the last round.

Pawn shop may contain guns for people who don't have one yet. Most pawn shops I've seen are pretty junky and probably in bad shape after looting.

If the second floor has camping equipment, it might be the best inventory option, even if it also carries the greatest risk. @ironshield
