The Last Stand is a fantastic flash web based game in which you play as a survivor of a zombie apocalypse. You stand behind a cruddy barricade on the right of the screen and must use the mouse to shoot zombies advancing from the left until daybreak comes. The zombies come at various speeds, mostly walking, but some sprinting. If your barricade breaks before daylight your dead.
Daylight takes place on a stat screen. You have 12 hours to which you can allocate to different tasks - repair the barricade, search for survivors, and search for weapons. This cycle repeats until you inevitably get eaten. A really fun, surprisingly gloomy quick game, though not too much to it.
