It's not often we'd rush to post about a Japan-only licensed anime game for PSP ... but the latest Evangelion game revealed by Famitsu is a little unusual. Rebuild of Evangelion Sound Impact, is, as the title suggests, a rhythm game based on the Evangelion anime series. It's also being developed by Grasshopper Manufacture, led by Doshin the Giant creator Kazutoshi Iida. It also has over 30 tracks of music from the series, arranged by Akira Yamaoka.

If you were, separately, a fan of Grasshopper Manufacture, Yamaoka, and Evangelion, well, now those fandoms are connected, and you're freaking the hell out. We're, um, guessing. Rebuild of Evangelion Sound Impact is due for release in Japan September 29, with two separate special editions containing either a soundtrack, or a soundtrack plus a t-shirt and headphones. Good thing the PSP is region free!
