No, hell hasn't frozen over, those aren't winged mutant pigs flying outside your window, and Half-Life 3 isn't littering the bargain bins at your local GameStop. Indie developer and publisher Curve Studios is releasing Stealth Inc 2--a sequel to the critically acclaimed Stealth Inc: A Clone in the Dark--exclusively on the Wii U later this year.

"The good thing about releasing on Nintendo is, you're not competing with a lot of other people," Curve Studios' Marketing Manager Rob Clarke told Gamespot. "Even as an indie publisher we always fight with AAA for space on the storefront. With Nintendo, we know they're gonna support us. We also know that we're not having to compete with, say, Watch Dogs for example."

"Yes, there'll be [Mario Kart 8]. But because Nintendo plans its first games out so well, and they have so much control over first-party stuff, we know where we fit into its plans. It's a different experience to working with Sony, but hopefully it'll pay off."

Stealth Inc 2 sees players return to PTi Industries, but this time with full run of the facility rather than just its test chambers. New equipment is promised, as well as co-operative play via the Wii U GamePad.

With all the doom and gloom surrounding the Wii U, and with many third-party publishers pulling support for the platform, an exclusive Wii U release is a risky move, or at least one that potentially limits Stealth Inc 2's audience.

"You get a bigger share of [the Wii U's] smaller audience", game director Jonathan Biddle told GameSpot. "There are less games being released on Wii U, so we'll get more time in the spotlight."

"We're kind of relishing the idea of being on Wii U. Us being exclusive to Wii U is gonna be news, people are gonna talk about it. No one's gonna miss this fact. That's what we're hoping will make up the difference. It's also good to be on the platform that's got all these unique features. We're gonna be supporting the gamepad, and it's nice to stretch your design muscles a bit harder."

The original Stealth Inc: A Clone in the Dark was released on PlayStation 3 in July of last year, with the PC version making its retail debut as Stealth Bastard Deluxe in 2011. For more on the game, check out GameSpot's review.
