The two installments of the shoot ’em up Deathsmiles will arrive in physical format on June 30 in News › Brief

Deathsmiles 1 is a fun game in its own way, a nice surprise when it came out on xbox360. I imagine that both games are backwards compatible on xbox and that is why they will not have a physical version.
They could also already release Deathsmiles 2 on PC because there are always people who want more of this type of game.
