such as Contra and Metal Slug, as well as newer
bullet hell shooters.

While typically you see a bevy of
bullet hell shooter variations due to the franchise's origins, you also see some quite different approaches

such an interesting meld of open RPG, twitch action, platformer,
bullet hell shooter that shouldn't be ignored by anyone.
