Most of the above games are NTSC-J region locked, some have had a release in the US and Europe, where possible I have linked to the release for each region.

I intend to develop this list more in the future, however for now enjoy the list of all the current Shoot Em Ups released for the Xbox 360, Note the links are affiliate links.

Which would you recommend, and are there playable demos for these games?

Just hope they're not region locked like LoveFOOTBALL was.

Eschatos is Region free so you can order it from Japan and it'll work on your console anyways, not sure about the Wonder Version though.

Region Free:

Mushihimesama Futari (1.5)
ESPGaluda II
Muchi Muchi Pork & Pink Sweets
Bullet Soul
Eschatos

Got a PAL release:

Death Smiles
Akai Katana Shin
Dodonpachi Resurrection

Of the PAL / Region free games on the list i would get:

Dodonpachi Resurrection
Akai Katana Shin
ESPGaluda II
Mushihimesama Futari

On the JPN marketplace you will find demos of Raiden Fighter Aces and Akai Katana Shin that are not region locked.
