Besides the thrill of shooting zombies, there's also the thrill of getting caught by your teacher when playing this on the school computer

Played as part of the Legacy Collection, the sequel is a small expansion and reformatting (using many of the same assets and, to my recollection, no new enemies) of the first game. I appreciate these expansive elements, but like the first it is all just too easy and not worth replaying.

A substantial and marked improvement over The Last Stand, I think this is as good as flash games got. Which was perfectly acceptable, given I was about 8 or 9 when I played it.
