Operation Raccoon City Cameos from other games.

My favorite nostalgic location was (and I don't remember the scenario name, but it's the one where at the end you fight two T-103's) you can see Kendo's Gun Shop while fighting a bunch of Hunters...Too bad you can't go inside...It's actually right after you first see Leon and he runs off...

Yep, Kendo's Gun Shop is also present in a multiplayer level, I think Apocalypse. From the USS spawn, outside, left side and a few meters ahead.

Zombies make a cameo in this game. I never saw that one coming
