Konami is releasing a bunch of classic game collections to mark the video game giant's 50th anniversary.

The Konami Anniversary Collections will focus on three major game franchises: Castlevania, Contra, and Konami's Arcade Classics. They'll be released digitally on PlayStation 4, PC, Nintendo Switch, and Xbox One.

Players will also be able to enjoy a bonus eBook, 'packed with new information about the titles, including interviews with the development staff, behind-the-scenes insights, and sketches and design documents never before revealed to the public!'

Konami will launch the Arcade Classics lineup first, which includes Haunted Castle, Typhoon (A-JAX), Nemesis (Gradius), Vulcan Venture (Gradius II), Life Force (Salamander), Thunder Cross, Scramble, and TwinBee. It's out on April 18, priced $19.99.

The Konami Castlevania Collection is up next, and arrives this summer. There's eight games in the bundle, although only four have been announced so far: Castlevania, Castlevania II: Belmont's Revenge, Castlevania III: Dracula's Curse, and Super Castlevania IV.

Finally, the Contra Anniversary Collection, also due this summer, features eight games. Again, Konami's only unveiled four of them so far: Contra, Super Contra, Super C, and Contra III: The Alien Wars.
