Ikaruga is one of those games that can't be ported enough. The vertical shoot-'em-up is a bona fide gem, the kind of shmup that even people who "don't really mess with shmups" can learn to love.
A recent listing with Germany's ratings board suggests that we'll see the game again before long, and its next stop is going to be on PlayStation 4. Treasure is handling the port, according to the USK.
The last time we saw Ikaruga was four years ago, on Steam, so it's been a while. And as much as it probably goes without saying, I hope Treasure has more than just PS4 plans in mind.
