Microsoft’s ID@Xbox program, which is responsible for bringing indie titles to the Xbox One, may have a wide range of titles scheduled for the next few months but some developers are still avoiding it due to the parity clause. Speaking to Digital Spy, Curve Digital’s managing director Jason Perkins says it’s the reason that titles like MouseCraft, The Swapper and Titan Attacks won’t be on the Xbox One.

“Unfortunately, all these titles here get ruled out by the parity clause.”

Design director Jonathan Biddle also stated that, “We feel like it’s unnecessary handcuffs really, but that’s the way they’ve decided to run that. We’re platform agnostic. We’ll support everyone. What works for us is having many as healthy competitors as possible. They’ll all try and promote the games they’ve got, and that’s what we want. We want a healthy ecosystem, so we want everyone to do well.”

The aforementioned parity clause states that developers must release their games on the Xbox One at the same time as other formats. It’s become a big issue for some developers who have specific time frames for other formats or might want to bring the indie title to the Xbox One later. And it won’t be disappearing any time soon. Stay tuned for more information.

Indie development team Curve Studios has announced that you can now download its tribute to ’80s arcade platformers, Titan Attacks! for the PS3, PS4 and PS Vita via the PlayStation Network for $11.99. “You can spell it with or without the exclamation mark,” Curve Studios PR and Marketing Manager Rob Clarke jokingly writes on the PS Blog, “but we think it adds that extra level of excitement if you keep it in.”

“We’ve been working on Titan Attacks! here at Curve since the holiday,” Clarke further said. “It’s our very first PS4, PS3, and PS Vita cross buy game. One of the cool things we’ve seen with Titan Attacks! during development has been just watching people play the game.”

Clarke goes on to talk about what he thinks makes Titan Attacks! (with an exclamation mark, yes) so special.

“Part of the appeal is the fact Titan Attacks! is instantly accessible and understandable to anyone who has played arcade games before,” Clarke wrote. “But while the game may look simple on the surface and very “retro” in its style, there’s actually a lot going on that keeps the game interesting, fresh, and addictive through all one hundred levels of the campaign.”
