The game looks like a standard email inbox, with new emails stacking up at an alarming rate (each one making that spine-chilling "bing" noise). But instead of having to read them, you shoot them like space invaders of Atari fame, and they shatter into bits before evaporating. Special keystrokes would allow you to shoot dozens with a single shot. Bonus points for hitting emails with attachments. Unlike conventional video games, where finishing a wave immediately advances players to the next wave, players of Email Invaders are "rewarded" by getting a 24-hours pause to the game -- no new emails for a full day. The next, more difficult wave becomes available the next day.
