Bummed that the Space Shuttle launch got scrubbed and need a pick-me-up? Have nothing to do this weekend? Are you totally out of iTunes credit and want a new game to play? Well, I have the solution to all three of these problems, and potentially any other problems you can cook up: Physics Gamebox [Free]

While you're waiting for the game to download (you are downloading it, aren't you?) you can check out our review. In a nutshell, Physics Gamebox comes packed with two incredibly popular games that got their start on various Flash game portals out there. Ragdoll Cannon has you shooting ragdolls at goals (and actually was the inspiration behind Ragdoll Blaster) as well as Roly-Poly Cannon which puts you in charge of firing your cannon at Roly-Poly bugs who have invaded. 300 levels in all are included, which should keep you busy for quite a while.

Earlier this week Epic Games reported that LucasArts signed a multi-year studio-wide licensing agreement to utilize Epic's awesome Unreal Engine 3 across multiple platforms. According to Epic Vice President Mark Rein, "LucasArts is now primed to capitalize on Unreal Engine 3's ability to scale across platforms, from mobile, through PC and console all the way up to the next generation of games."

Now, I'm not entirely sure just how excited to get about all of this. Epic Citadel [Free] and Infinity Blade [$5.99] have done a great job showing just what the Unreal Engine 3 can do on the iOS platform. Technically speaking, if games are developed in UE3 with multiple platforms in mind, targeting iOS devices could all be part of the same development process that would result in Xbox 360, PS3, and PC games. Rein does specifically mention mobile gaming too, and there's no disputing the fact that iOS is a main mobile platform currently.

However, LucasArts really has yet to get that involved in the world of iOS. Their App Store catalog is fairly barren, and only consists of Monkey Island remakes. I'd love to think that we're about to get a bucket of amazing LucasArts Unreal Engine 3-powered games dumped on the App Store, but if this is just being announced now, it will likely be quite a while before we see any of the projects utilizing this engine.

Keep your fingers crossed, iOS-owning LucasArts fans!

Fishlabs' highly anticipated add-on to Galaxy On Fire 2 [$9.99 / Lite] recently hit the App Store, and is likely sitting in your pending updates listing if you already own the game. (Assuming of course you haven't already updated.) This update actually comes in two parts, a free component and the actual Valkyrieadd-on which is unlocked via a $4.99 in-app purchase.

In this update, everyone who owns Galaxy On Fire 2 will be granted access to three ships from the original Galaxy On Fire: The Phantom, Vol Noor, and Wraith. Also, you'll be able to get a personal space station to store multiple ships as well as all your loot, cargo, and other items that you want out of your ships' cargo holds.

The Valkyrie add-on picks up on Keith T. Maxwell's adventures, and is largely based around fan feedback. Aside from a new array of planets, ships, weaponry, and other equipment, there's also an entirely new extensively voiced over campaign. The repair robots and automated turrets sound particularly useful, and a new black market trading system will allow players to get even more involved in the galaxy's virtual economy.

For more information on our game, you can check out our review, the insanely active forum thread, or Fishlabs' own incredibly interesting developer diary for the whole add-on project. I've had a great time with Galaxy On Fire 2, and look forward to delving deeper into this new add-on. The cost of the game and this new add-on might seem expensive in App Store terms, but the amount of content in the original game and now this new add-on is nothing short of ridiculous. I'm not exaggerating at all by saying if Galaxy On Fire 2 sucks you in, it could keep you busy for months.

Need more RPG fantasy action? Cool, because another big title based on these three things is now available for purchase on the App Store. The game I'm talking about here is Zenonia 3: The Midgard Story [$4.99], following Zenonia [$1.99 / Free] and Zenonia 2 [$1.99 / Free] as the third installment in the series.

This specific iteration offers a few new things � foremost being the "Fairy helper system," which adds some additional depth to the leveling mechanic. There are also a total of four character classes, more special active and passive skills, as well as a new, more streamlined inventory and item management system.�Oh, and if you're down with some Words With Friends style asynchronous play, Zenonia 3 has that � there's a special "Execution Room" which allows "co-op" play for loot, as well as PVP.

If you need a sense of what this game is about, check out this trailer. It's a little flashy, but there's some actual gameplay at the end:

The Zenonia games have always had a massive fan following on our forums, and the latest installment is no different. The thread has grown to an impressive size, and is worth checking out for the many impressions and gameplay tips left by readers.

If you've never heard of The Impossible Game [99� / Free]] go ahead and take a minute to clear your schedule because your going to need some free time. Released just over a year ago on the App Store, The Impossible Game is a port of the highly popular Xbox Live Indie game under the same name. While it's a platformer by nature, there's one major difference about The Impossible Game that really makes stand out from the rest: As the title might suggest, this game is hard.

The game's graphics consist of only 2 shapes, squares and triangles. The Impossible Game won't win any awards in the graphics department it makes up for it with some of the most original platform gaming I've ever experienced. The gameplay is simple and straightforward and consists of a square that moves automatically through a level at a blazingly fast speed while you try to tap on the screen to make your square jump over and onto other squares, all while trying to avoid smashing into them head on.

When you fail (and you will) and hit a box or land on some spikes you will automatically start right back at the beginning of the level and start over from scratch. Luckily there is a practice mode which allows you to place flags down as you progress through the the level so you can restart from your last dropped flag, but what makes this game so "impossible" is to truly beat a level you must make it all the way through from start to finish with only one life.

Even though it looks like a simple platformer from the outside this game still feels unlike anything I've ever played before, due in part to the way the levels are setup with the boxes in some crazy configurations with some needing to be climbed like an endless staircase and the rest needing to be precisely timed with the perfect jump or release of the screen, all the while moving at sonic speed.

The music consists of catchy techno beats that really tie in the precision jumping with the the frantic gameplay to perfectly produce a platforming package that I've yet to experience anywhere else. Even after a couple hundred plays through, the music still felt like a critical part to beating the game and not once did I want to turn it off as it seems to really help you to time jumps to sections in the song.

Because of the difficulty of this game, If you find you have the patience to finally beat these levels you will truly feel you have accomplished something amazing in a video game… Even if the reward at the end of a level is lackluster to say the least.

Keep in mind it will get quite frustrating to beat a level in one life, but once you do, it will be burned into your memory for life as a result of (potentially) hundreds of retries. This may somewhat diminish the games replay value, but I still continue to pick it up from time to time to see if I've still got it. Regardless, the game comes standard with two levels, each of which should take you quite some time to beat. If you're looking for more there's also a 99� IAP level pack to add an additional two levels.

Sure The Impossible Game came out quite a while ago, but it's still a ton of fun. If you liked the game on the Xbox 360, you'll likely enjoy it just as much on the iPhone. Otherwise, if you're the kind of person who gets into brutally difficult games and doesn't mind endlessly retrying levels until you get it right, look no further than The Impossible Game.
