[Every week GameSetWatch editor-in-chief Eric Caoili rounds up the latest news/media for obscure and offbeat games from IndieGames.com's sister site and alternative video game blog.]

Over at our recently resdesigned alt video game blog GameSetWatch, we shared a number of fun stories during the past week, including an online Puzzle Bobble released in Korea with social gaming elements, an expensive looking Trasformers pinball trailer, and more.

Thanks to the financial success of its first game, Limbo, developer Playdead Studios has bought itself back from its investors -- a move that grants the studio greater financial and creative independence.

The announcement came from investment bank GP Bullhound, which advised the sale. Playdead is now solely owned by its founders and management.

The founders of Playdead said that they were able to buy back the company due to the strong performance and success of Xbox Live Arcade and PC platformer Limbo.

Limbo was initially funded solely by founders Arnt Jensen and Dino Patti, with help from the Danish government. Investors were later brought in to help expand on the original concept. Gamasutra has contacted Playdead for comment on the buyback.

Playdead revealed earlier this week that it will be developing its next title using the Unity platform, noting that the decision was in aid of cutting down on the amount of work needed.

Hawken is an upcoming multiplayer FPS, with combat taking place solely in mech walkers and vehicles. The above trailer was released recently, showing off a bit of gameplay, along with the basic storyline.

The initial footage feels a little laggy and I found myself saying "come on, get to the actual game"... but once it gets going around the 1:10 mark, it looks like a real beast of a title, with plenty of blasting action and smooth, slick visuals. Hopefully not every map is as grey and brown as shown in this video, but hey, everything on display is pretty beautiful anyway, so I can't complain too much.

There's no release date as of yet, nor specific platforms, but you can keep tabs on the game via the Hawken blog. (Cheers Megan!)

Here's an upcoming action puzzler that with a dark side - you are A Virus Named Tom, and you've been released into a world of robots and technology to shut them all down. Via a series of grids, you're left to switch and flip pieces around, creating a clear path for the virus to spread.

While the first batch of levels appear to be pretty simple - at least from what the trailer shows anyway - the game soon ramps up the heat and you'll need to plan your routes appropriately if you want to dodge all the security systems that are trying to end your life. The most intriguing aspect for me is the multiplayer, as both the co-op and versus elements look like a ton of fun. Let's just hope it's online multiplayer and not just local!

The game is penned for a release later this year, and the dev team hopes to fire out PC, XBLA and PSN versions. Check out the official site for more details, and jump below the cut for a video that shows the multiplayer in a little more depth.

Oh, my god. Although I have absolutely no clue as to how effective the physics of this game might be in practice, Mari0 is awesome simply on the basis of the fact that it exists.

I mean, seriously. Just, look at it. It's the Super Mario Brothers. With a portal gun. It's Goombas being launched into the abyss. It's Koopa shells being shot through portals. It's Super Mario Brothers And Portal. Together. In the same game. Things do not get any better than this. At least, not for a while.

Now, go watch the trailer and be delighted in strange new ways this mid-week morning.

Unity Technologies has announced the finalists that will compete for the 2011 Unity Awards, to be given out during the 5th annual Unite 2011 conference in San Francisco's Masonic Center next month.

This might be stretching the definition of 'indie' as far as it might possibly go but I couldn't quite resist sharing this anyway. Perihelion is, in a word, old. Of course, that is only to be expected given the fact that it's a game for the Commodore Amiga.

According to Edvard Toth, the chap who was responsible for the art, rule-set and design of this post-apocalyptic title, Periphelion has not been distribution commercially for over 15 years. Nonetheless, it's being available again. By him. For free. With, of course, the assistance of Marek Tarnawski, who supplied Toth will all the files necessary to faciliate this.

Gloriously retro and apparently one of the better games ever released on the platform, this one is for all the cyberpunk/post-apocalyptic future fans out there.

You can download the game (and all other required files) here.

Though I'm still leery of the genre on the whole, things like Dusk ~ A Moonlight Romance ~ are slowly making a convert out of me. Then again, Dusk is also a rather delightful parody of a certain vampire-laden franchise so I might be a little biased. In fact, I'm probably extremely biased here. Who doesn't like poking fun at the glittery, melodramatic vampires of twilight?

In the words of the developer, Dusk features 'two unbelievably gorgeous guys' and '4k words of scintilliating text'. It's unabashedly tongue-in-cheek without being outright offensive, something that might make it palatable for those who actually enjoy the Twilight series.

Dusk ~ A Moonlight Romance ~ is free-to-download and can be found here in the Lemmasoft forums.
