Remember back in the 1970s and '80s when you played Asteroids, Galaga, Missile Command, and Space Fury for hours? Here's a browser game from Pixeljam that will put you back into those days when graphics were simple and you didn't have to learn any fantasy history or consult maps or create a character to get started. Utopia Must Fall is an old-fashioned shoot-em-up in which you must protect your city from invading aliens, falling boulders, and bombs. There are nukes, too. After the first round, you can upgrade the physics of the game a little to improve your kill rate, or else launch a new strategy. The vector graphics are simple, but still attractive in all their neon glory. When was the last time you played a game on a black background?
In the first run through, I only managed to protect the population of London for three days, but I had a lot of fun doing it, and that's the whole purpose of a game, isn't it? Sorry, London. The browser game is just a demo for a full version that will be released in the next couple of months. -via Metafilter
PS: If the game asks for a password, it is CEASEFIRE.
