If you still haven't followed my previous two recommendations and checked out either A Kingdom for Keflings or its sequel, A World of Keflings, you owe it to yourself to check those out before reading any further. Though both are hard to categorize or accurately describe, both represent the oddly Zen-like flow state that the best of games feature beautifully. They're the sort of game where you'll lose hours on end doing seemingly nothing, and you'll love every minute of it.

For those who took my suggestions and checked the previous games out, NinjaBee is back again with the first DLC content pack for A World of Keflings, A World of Keflings: It Came From Outer Space. The new expansion adds another 2 - 3 hours of Keflings fun, including new resources, buildings and a plethora of science fiction related humor. It's also a lot of fun too.

A World of Keflings: It Came From Outer Space is more fun with the Keflings. The game retains all of the charm and gameplay found in previous games, only adding an intergalactic spin as a group of Kefling-like aliens crash land in the Keflings' homeworld and search for a way to repair their ship.

Gameplay remains largely unchanged from past games. You play as a giant (represented as your XBL Avatar) who helps the little Keflings build their village. Each mission involves setting up tiny assembly lines of Keflings harvesting resources and bringing them to their corresponding buildings. From there, you can build smaller parts needed to construct larger buildings.

Structures are slightly different in It Came From Outer Space. Rather than including a bunch of specialized structures, each structure is split into a couple of specialized types. For instance, the normal refinery (a giant, caged space lobster) normally produces bricks when fed sand. After feeding it a space carrot, however, it can produce radioactive ore, which is needed for certain structures. The new setup doesn't alleviate the need for multiple buildings, though it does offer some flexibility in your build strategy.

It Came From Outer Space also makes it easier to keep track of which workers are doing what. Once assigned to a task, the alien's head takes a different shape that is easy to quickly pick out from the crowded space.

Although the new structure type mechanic isn't a major space saver, if you work the system right, you can free up a little breathing room. This, as it turns out, is incredibly important. A World of Keflings: It Came From Outer Space isn't the most spacious of maps, coming in at about the same size as the Ice or Desert Kingdoms in World of Keflings. It's enough space to move around and explore, but small enough that you may run into some workflow problems. You need to keep structures pretty close to each other to keep production levels up, which is why you want to figure out how to best use the "type switch."

The execution behind It Came From Outer Space isn't the best. Although the game essentially adds another "race" to the Keflings' world, the alien adventure is a completely separate entity. In fact, I wasted an hour or two of time in World of Keflings waiting for the DLC to kick in. There's nothing (well, nothing really noticeable) to indicate you need to start another chapter to play the DLC content. I'm sure it would have caused a few problems, but some integration with the original would have been welcome.

A World of Keflings: It Came From Outer Space is a great buy for Keflings fans looking for another short dose of resource management/ building fun. It doesn't bring anything exceptionally new to the game, though it does offer a couple of really neat enhancements that offer a snapshot of what I suspect we might see in a future release. Even without any major additions or overhauls, it is still an enjoyable experience overall. The Zen trance-inducing gameplay is all here, guaranteeing you won't get anything done in the real world once you start playing around in the Keflings' world, and it is smart and funny.

It Came From Outer Space comes with high recommendations for any Keflings fan and a massive plea for non-fans to give the series a try.
