Chakan: The Forever Man is a fairly standard platform game in which you control a dead guy (Chakan has lost his soul) through many levels of hack and slash platforming. The ultimate goal is defeat all the bad-guys and so finally achieve inner-peace.
The story-line (if you can call it that) does give this game an interesting image and it is much darker than most other titles available on the Genesis.
This is a full completion run, which, compared to the any% branch, beats some additional levels and collects all items.
NOTE: Don't be fooled by the fake credits after the final level. The game is not quite over yet.
