Basically, this came out on PC and was well received, though some had issues with it. It was a good shmup with really pretty graphics and a good soundtrack, and the PC packaging was quite substantial, including a booklet with lots of backstory, art, and game info. Now there's a retooled PS3 release you can grab on PSN for ten bucks, and it's apparently much better than the PC version was. I guess the developer is very active on their forums, and they've spent a lot of time talking with fans and listening to complaints. It's a shame that this didn't result in a brand-new PC version with all the improvements, but I imagine their sales had to be somewhat lacking on that platform. It's a niche genre to begin with, and not one with a tremendously big PC legacy.
Anyway, the basic idea is a chain system: shoot guys until you build up a meter, then switch your weapon and start building more chain. Do this repeatedly and you get tougher and tougher chains to complete, and there's a bonus at the end of each, eventually making your ship much more powerful. And, of course, since this is a super-tough shooter along the lines of
Ikaruga, this is absolutely necessary to progression, and knowing which weapon to have out at any given time is pretty helpful too. A lot of people complained that they felt really underpowered, but I think that's somewhat intentional, because it makes the choice of weapon at any given time a more important one.
I tried it out earlier and I quite enjoyed it. I think this is one I'll be picking up. Ten bucks on PSN doesn't seem like a bad deal at all.
The last shot there you can see has a different interface. That's the PC version. I think I actually prefer the HUD there, but I guess it's clearer and more informative in practice on PS3, if a bit less sleek.
