To quote the intro of Fallen City, Channel 4 and Big Robot's educational puzzle/real-time strategy game: What is a city? It is a machine; a machine for living in. But all machines can break down. The inhabitants of Fallen City (Angries) have become distracted by their individual lives and dreams and have let the once gleaming metropolis fall into disrepair. Frustrated by their inability to live the lives of fame and fortune they were told could satisfy them, many of the Angries fell into boredom or rage... and the city sunk ever deeper into its gloom. But broken machines can be fixed, right?

The world is in your hands in Red Redemption's sequel to 2007's Climate Challenge. Assume control of the newly formed GEO in this complex and challenging strategy simulation game that forces you to cope with the needs of not only the environment but the people who live in it in order to change the future, dealing with the issues afflicting each country throughout the world as you try to bring about change. Real science and research guides your decisions, and Fate of the World offers up a challenging, complex experience that might get you thinking in more ways than one.

Certainly we know about the immediate dangers of the undead: the biting and the clawing and the infecting and the whatnot. What about the larger environmental concerns? I mean, a zombie claws his way out of a shallow grave... who's going to be re-sodding that ground? A vampire explodes in a fiery cloud of dust... someone needs to sweep that up. And don't even get me started on what can happen when a werewolf gets in your flower bed. 3kggames's new action looper Dirt of the Dead shows that the clean-up can get just as intense as the confrontation.

Playing God has a bit of a poor reputation: the kind of reputation that leads to torch and pitchfork wielding villagers smoking you out of a burning windmill. However, Alxemy, the new Doodle God-esque puzzler by Hyptod, reminds us that sometimes combining elements to make new life feels more like toying with a new Lego set, rather than a crime against nature.

Not satisfied simply to have won second place in our last competition, game designer Lars Doucet has been busy reworking, researching, and refining his entry, the strategic defense game Super Energy Apocalypse. We are proud to announce that the full-fledged game has now been released!

Super Energy Apocalypse, 2nd place prize winner in our 5th game design competition, plays a bit like a tower defense game, in that most of the time is spent getting ready for the next wave, and the player is offered no control over the targeting of the enemies. Planning for the battle is the critical strategic element, rather than the battle itself. The zombies come out only at night, so use the daylight wisely!

ElectroCity is fun little Flash game intended "to spark an interest and lay an unbiased foundation for later learning" about the issues involved in power generation, cost, and environmental impact. It is obviously a very simplistic look at those issues, intended to give a broad overview and invite further research on the part of the player. It's also not a bad little town sim game to boot.

Developed by Red Redemption and funded by the BBC, the Flash-based Climate Challenge is a thoroughly researched, compelling resource-management sim. As the "President of the European Nations" you must radically reduce your people's carbon emissions over the course of a century, while remaining popular enough to stay in office.
